Sterling banknotes are the banknotes in circulation in the United Kingdom and its related territories, denominated in pounds sterling (symbol: £; ISO 4217 currency code GBP).
Sterling banknotes are official currency in the United Kingdom, Jersey, Guernsey, the Isle of Man, South Georgia and the South Sandwich Islands, and Tristan da Cunha in St Helena, Ascension and Tristan da Cunha. One pound is equivalent to 100 pence. Three British Overseas Territories also have currencies called pounds which are at par with the pound sterling.
In most countries of the world the issue of banknotes is handled exclusively by a single central bank or government, but in the United Kingdom seven retail banks have the right to print their own banknotes in addition to the Bank of England; sterling banknote issue is thus not automatically tied in with one national identity or the activity of the state. The arrangements in the UK are unusual, but comparable systems are used in Hong Kong and Macao, where three and two banks respectively issue their own banknotes in addition to their respective governments.
The Bank of England does act as a central bank in that it has a monopoly on issuing banknotes in England and Wales, and regulates the issues of banks in Scotland and Northern Ireland. Pounds issued by Crown Dependencies and other areas are regulated only by local governments and not the Bank of England.


Clydesdale Bank plc (Scottish Gaelic: Banca Dhail Chluaidh) is a commercial bank in Scotland. Formed in Glasgow in 1838, it is the smallest of the three Scottish banks. Independent until it was purchased by Midland Bank in 1920, it formed part of the National Australia Bank Group (NAB) between 1987 and 2016. Clydesdale Bank was divested from National Australia Bank in early 2016 and its holding company CYBG plc, trades on the London and Sydney stock exchanges. CYBG plc's other banking business, Yorkshire Bank operates as a trading division of Clydesdale Bank plc under its banking licence.
As with the two other Scottish banks, the Bank of Scotland and the Royal Bank of Scotland, Clydesdale Bank retains the right to issue its own banknotes.
In March 1838, an advertisement appeared for a new joint stock banking company in Glasgow, the Clydesdale Banking Company. It was
The driving figure behind the formation of the Bank was James Lumsden, a stationer by business, a councillor, police commissioner and, later, Lord Provost of Glasgow. Another member of the founding committee, Henry Brock, became the Bank's first manager. Brock came of a merchant family, was an accountant and one of the founders of the Glasgow Savings Bank. Despite the declaration in the advertisement, in the year after formation the Bank opened three Glasgow branches as well as its first country branches in Campbeltown and Falkirk; a further seven had been opened by 1844. These were supplemented by the acquisition of the Greenock Union Bank; formed in 1840, it had four branches in the Glasgow hinterland.
Following the purchase of the Greenock Union, there was little change in the structure of the Bank and there were still only 13 branches in 1857. In that year, Clydesdale became the first Scottish bank to produce a printed balance sheet, and it showed assets of £2.7m and net profits of £70,000. The public disclosure of its strength stood it in good stead, for only months later the Western Bank of Scotland closed its doors, followed the next day by the first closure of the City of Glasgow Bank. Clydesdale gained not only customers but 13 branches from the Western. A few months later came the acquisition of the Edinburgh and Glasgow Bank, which had been weakened by the same economic disturbances. The Edinburgh & Leith Bank, as it was originally, had been formed in 1838 "for the benefit of the 'industrious middle classes'" and it had bought the Dumfries-based Southern Bank of Scotland in 1842 and the Glasgow Joint Stock Bank in 1844, the latter leading to the change of name to Edinburgh & Glasgow Bank. Poor lending in the 1845–47 period, particularly to Australia, dogged the Bank for the next ten years and it was eventually taken over by the Clydesdale for a nil consideration; Clydesdale retained 19 of its 27 offices. Five years later, in 1863, Clydesdale acquired the more successful Eastern Bank of Scotland, like Clydesdale, also founded in 1838. Based in Dundee it was to have two separate offices and boards, one in Dundee, the other Edinburgh. Before opening for business it acquired the Dundee Commercial Bank to serve as its Dundee office. Difficulties with the two boards working together led to the Edinburgh bank being wound up and the Eastern became an essentially Dundee bank; its acquisition gave Clydesdale its first interests north of the River Tay.
Much of the growth in the Bank's network had come from acquisitions and the management remained cautious regarding direct branch expansion. However, in 1865, a committee was formed to look at prospects and 16 branches were opened in two years. In 1874 the Clydesdale went south of the border and opened three branches in Cumberland but this was seen as following existing trade rather than making a specific attempt to enter the English market. Indeed, Clydesdale was one of the last Scottish banks to acquire a London office (1877). In 1878, the City of Glasgow Bank failed for the second time, leading again to an increase in Clydesdale's deposits and the acquisition of nine of the Glasgow branches. The scale of the collapse led to further debate on desirability of limited liability and, following legislation in 1879 (allowing fixed uncalled liability on shares), Clydesdale Bank registered as a limited liability company in 1882.
Reid described the period 1890–1914 as "the tranquil years", but that did not preclude steady expansion of the branch network – from 92 to 153. That was to mark the end of Clydesdale's independent existence. In 1917 the Bank was approached by London City and Midland (later Midland Bank) and, although initially resisted, Clydesdale Bank was sold in 1920. However, it continued to operate independently and was always referred to as an affiliate, not a subsidiary. The Glasgow banks suffered more than others in the depressed economy of the inter-war period and from being the largest lender in Scotland in 1920, it fell to fifth place by 1939. Despite this, the Bank continued to open branches, particularly in areas enjoying export growth, and the network increased from 158 in 1919 to 205 in 1939.
Midland had also acquired the North of Scotland Bank in 1923 but the Aberdeen management had fiercely resisted any attempt to merge with Clydesdale. However, the changed competitive market after the Second World War meant that the two banks could not remain separate and in 1950 they were amalgamated to become the Clydesdale and North of Scotland Bank (soon shortened to Clydesdale Bank). Clydesdale had 189 branches and the North of Scotland 161, covering 221 towns between them. Of the eight Scottish banks, Clydesdale had been the third largest by deposits, the North being the smallest. The merged bank became Scotland's largest in terms of deposits, advances and branches. However, by 1969, mergers elsewhere had reduced the number of Scottish banks to three with Clydesdale now being the smallest. Midland needed to rationalise the enlarged Clydesdale but faced resistance. Midland also needed additional capital and its solution to both challenges was to sell Clydesdale (along with Midland's Irish subsidiaries) to National Australia Bank in 1987.
In 1989 National Australia Bank bought the Clydesdale bank for £420m. Fred Goodwin, an accountant working for Touche Ross, worked on the acquisition. In 1995 Goodwin, with little direct banking experience, was appointed deputy CEO of the Clydesdale until 1997. During this period Goodwin earned the nickname "Fred the shred" for his aggressive manner in dealing with staff.
In September 2013 the bank was fined £8.9m after miscalculating the mortgage repayments of more than 42,000 customers. In March 2015 the House of Commons Treasury Select committee said in a conduct report that they had evidence that the Clydesdale Bank had mis-sold unregulated Tailored Business Loans and that the bank's own internal review of the mis-selling had serious shortcomings and lacked transparency. In April 2015 the Clydesdale was fined £20.7m the largest of its type imposed by the Financial Conduct Authority for the mis-selling of PPI insurance.
National Australia Bank confirmed in October 2014 that it planned to exit the UK, and was considering a number of options for Yorkshire and Clydesdale Banks, including a possible stock market listing. In October 2015, NAB confirmed it would float Clydesdale Bank and Yorkshire Bank on the London Stock Exchange (LSE) in February 2016 through an initial public offering, with an aim of raising £2bn. The bank's newly formed holding company CYBG plc began conditional trading on the LSE and the Australian Securities Exchange on 3 February, and began trading unconditionally from 8 February. The flotation share price of 180p meant that the National Australia Bank made an estimated loss of £2bn on the sale and had to make provisions of around £1.7bn to cover claims for mis-selling of products.
In March 2016 CYBG announced the closure of 28 branches as a cost saving move. The following month, CYBG announced the closure of a further 9 Clydesdale branches and 17 Yorkshire Bank branches.



Archibald Campbell, 3rd Duke of Argyll, 1st Earl of Ilay (June 1682 – 15 April 1761) was a Scottish nobleman, politician, lawyer, businessman, and soldier. He was known as Lord Archibald Campbell from 1703 to 1706, and as the Earl of Ilay from 1706 until 1743, when he succeeded to the dukedom. He was the dominant political leader in Scotland in his day, and was involved in many civic projects.
Born at Ham House, Petersham, Surrey, he was the second son of Archibald Campbell, 10th Earl and 1st Duke of Argyll (1658–1703) and his wife Elizabeth, eldest daughter of Sir Lionel Talmash of Helmingham, Suffolk. He was the first cousin once removed of Lord William Campbell.
He was educated at Eton College and later at the University of Glasgow and then Utrecht University, where he studied civil law. He was appointed Lord High Treasurer of Scotland by Queen Anne in 1705.
He supported his brother, John Campbell, 2nd Duke of Argyll (on many topics, most notably the Act of Union), earning him the title of Earl of Ilay in 1706. Following the treaty of union he was elected as one of the sixteen Scottish peers to sit in the House of Lords.
His military career, which was less successful than his brother's, was somewhat distinguished. He obtained the Colonelcy of the newly formed 36th Regiment of Foot in 1701 and assisted his brother at the 1715 Battle of Sheriffmuir.
In 1711 he was appointed to the Privy Council. Many called him the "most powerful man in Scotland", at least until the era of Henry Dundas. Prime Minister Robert Walpole gave Campbell control over the royal patronage in Scotland. That became his base of power; he used it to control the votes of the other Scottish peers in the election of 16 representative peers to the British Parliament in London.
Lord Ilay played a critical role in establishing The Faculty of Medicine at the University of Edinburgh in 1726.
He was one of the founders of the Royal Bank of Scotland in 1727, and acted as the bank's first governor. His portrait has appeared on the front of all Royal Bank of Scotland banknotes, and as a watermark on the notes, since they were redesigned in 1987. The portrait is based on a painting by Allan Ramsay, in the Scottish National Portrait Gallery.
He succeeded his brother to the title of Duke of Argyll in October 1743. He worked on Inveraray Castle, his brother's estate, which was finished in the 1750s; however, he never lived in it, and he died in 1761. He is buried at Kilmun Parish Church.
He was married to Anne Whitfield about 1712, but had no legitimate male issue at his death. In his will, he left his English property to his mistress Ann (née Shireburn) Williams. His titles passed to his cousin, the son of his father's brother John Campbell of Mamore.
The Duke established an estate at Whitton Park, Whitton in Middlesex in 1722 on land that had been enclosed some years earlier from Hounslow Heath. The Duke was an enthusiastic gardener and he imported large numbers of exotic species of plants and trees for his estate. He was nicknamed the 'Treemonger' by Horace Walpole. On his death, many of these, including mature trees, were moved by his nephew, the third Earl of Bute, to the Princess of Wales' new garden at Kew. This later became Kew Gardens and some of the Duke's trees are still to be seen there to this day. The Duke of Argyll's Tea Tree is an imported shrub named after him which has become established in hedgerows in some parts of England.
