The Principal Private Secretary to the Prime Minister is a senior official in the British Civil Service who acts as Principal Private Secretary to the Prime Minister of the United Kingdom.
 The holder of this office is traditionally the head of the Prime Minister's Office.
 In the Civil Service, the role is currently graded as a Director-General.
 To date, no woman has ever occupied the office.
 In fiction, the character of Bernard Woolley in the television series "Yes, Prime Minister", occupied this post.
The Prime Minister of the United Kingdom is the head of the Government of the United Kingdom, and chairs Cabinet meetings.
 There is no specific date when the office of Prime Minister first appeared, as the role was not created but rather evolved over a period of time.
 The term was used in the House of Commons in 1805 and it was certainly in parliamentary use by the 1880s, and in 1905 the post of Prime Minister was officially given recognition in the order of precedence.
 Modern historians generally consider Sir Robert Walpole, who led the government of Great Britain from 1721 to 1742, as the first Prime Minister.
 Walpole is also the longest-serving Prime Minister by this definition.
 However, Sir Henry Campbell-Bannerman was the first Prime Minister and Margaret Thatcher the longest-serving Prime Minister to have been officially referred to as such.
Official Secretary to the Governor or Official Secretary to the Governor-General is an office in the Government House in various British overseas territories and Commonwealth realms.

 In some countries or territories the titles Private Secretary, Personal Secretary or simply Secretary are used instead of "Official Secretary".
 The Official Secretary is usually the general manager of the Government House, although he or she may have additional functions.
 In New Zealand and Canada, e.g., the Official Secretary is a civil service officer from the Prime Minister's Department or Office, but in Australia, the Official Secretary has become a position independent from the government.

Clement Richard Attlee, 1st Earl Attlee, {'1': ", '2': ", '3': ", '4': "} (3 January 1883 – 8 October 1967) was a British Labour politician who served as Prime Minister of the United Kingdom from 1945 to 1951 and Leader of the Labour Party from 1935 to 1955.
 In 1940, Attlee took Labour into the wartime coalition government and served under Winston Churchill, becoming the first person to hold the office of Deputy Prime Minister of the United Kingdom.
 He went on to lead the Labour Party to an unexpected landslide victory at the 1945 general election; forming the first Labour majority government, and a mandate to implement its postwar reforms.
 The 12.0% national swing from the Conservatives to Labour was unprecedented at that time and remains the largest ever achieved by any party at a general election in British electoral history.
 He was re-elected with a narrow majority at the 1950 general election.
 In the following year, Attlee called a snap general election, hoping to increase his parliamentary majority.
 However, he was narrowly defeated by the Conservatives under the leadership of Winston Churchill; despite winning the most votes of any political party in any general election in British political history until the Conservative Party's fourth consecutive victory in 1992.
 Attlee remains the longest-ever serving Leader of the Labour Party.

The later life of Winston Churchill documents the life of the British statesman from the end of World War II and his second term as Prime Minister of the United Kingdom, until his subsequent death and funeral in 1965.
 After the end of the war Churchill had to step down as Prime Minister of the United Kingdom because the Conservative Party lost the 1945 election.
 For six years he was to serve as the Leader of the Opposition.
 During these years Churchill continued to influence world affairs; in 1946 he gave his Iron Curtain speech which spoke of the expansionist policies of the USSR and the creation of the Eastern Bloc; Churchill also argued strongly for British independence from the European Coal and Steel Community (which he saw as a Franco-German project as Britain still had an empire).
 In the General Election of 1951 Labour was defeated and Churchill became Prime Minister for a second time.
 Churchill continued to lead Britain but was to suffer increasingly from health problems.
 Aware that he was slowing down both physically and mentally he resigned from the Cabinet in 1955.
 However he continued to sit as an MP for Woodford until he retired from politics in 1964.
 Churchill died on 24 January 1965 and was granted the honour of a state funeral.
 He was buried in his family plot in St Martin's Church, Bladon near to where he was born at Blenheim Palace.
