The Iron Lady is a 2011 British-French biographical drama film based on the life and career of Margaret Thatcher (1925–2013), a British stateswoman and politician who was the longest-serving Prime Minister of the United Kingdom of the 20th century.
 The film was directed by Phyllida Lloyd.
 Thatcher is portrayed primarily by Meryl Streep, and, in her formative and early political years, by Alexandra Roach.
 Thatcher's husband, Denis Thatcher, is portrayed by Jim Broadbent, and by Harry Lloyd as the younger Denis.
 Thatcher's longest-serving cabinet member and eventual deputy, Geoffrey Howe, is portrayed by Anthony Head.
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.
The Prime Minister's Official Spokesperson or alternatively Prime Minister's Official Spokesman/Spokeswoman is a position in the United Kingdom's Civil Service, located in the Prime Minister's Office in 10 Downing Street and used by the British Prime Minister to convey information to the public.
 The Prime Minister's Official Spokesperson usually addresses a small group of press and media correspondents, known as lobby correspondents, each morning to deliver statements on current events on behalf of the Prime Minister.
Begum Ra'ana Liaqat Ali Khan (Urdu: ‎ , born Sheila Irene Pant; February 1905 – 13 June 1990), was one of the leading woman figures in the Pakistan Movement along with her husband Liaquat Ali Khan, and a career economist, and prominent stateswoman from the start of the cold war till the fall and the end of the cold war.
 Ra'anna was one of the leading woman politicians and nationwide respected woman personalities who started her career in the 1940s and witnessed key major events in Pakistan.
 She was one of the leading and pioneering woman figures in the Pakistan Movement and served as the executive member of Pakistan Movement committee working under Muhammad Ali Jinnah.
 She also served as economic adviser to Jinnah's Pakistan Movement Committee and later became First Lady of Pakistan when her husband Liaqat Khan Ali became Pakistan's first prime minister.
 As First Lady of Pakistan, she launched programs for woman's development in the newly founded country.
 Later, she would start her career as a stateswoman that would last a decade.
Margaret Hilda Thatcher, Baroness Thatcher, {'1': ", '2': ", '3': ", '4': "} (née Roberts ; 13 October 1925 – 8 April 2013) was a British stateswoman who was Prime Minister of the United Kingdom from 1979 to 1990 and Leader of the Conservative Party from 1975 to 1990.
 She was the longest-serving British prime minister of the 20th century and the first woman to have been appointed.
 A Soviet journalist dubbed her the "Iron Lady", a nickname that became associated with her uncompromising politics and leadership style.
 As Prime Minister, she implemented policies that have come to be known as Thatcherism.
The Prime Minister of Northern Ireland was the head of the Government of Northern Ireland between 1921 and 1972.
 No such office was provided for in the Government of Ireland Act 1920, however the Lord Lieutenant, as with Governors-General in other Westminster Systems such as in Canada, chose to appoint someone to head the executive even though no such post existed in statute law.
 The office-holder assumed the title "Prime Minister" to draw parallels with the Prime Minister of the United Kingdom.
 On the advice of the new Prime Minister, the Lord Lieutenant then created the "Department of the Prime Minister".
 The office of Prime Minister of Northern Ireland was abolished in 1972, along with the contemporary government, when direct rule of Northern Ireland was transferred to London.
Streamlining the cities: Government proposals for reorganising local government in Greater London and the Metropolitan counties was a government white paper issued in 1983, by the Conservative government of Margaret Thatcher which led to the abolition of the Greater London Council (GLC) and the metropolitan county councils (MCCs).
The letters of last resort are four identically-worded handwritten letters from the Prime Minister of the United Kingdom to the commanding officers of the four British ballistic missile submarines.
 They contain orders on what action to take in the event that an enemy nuclear strike has destroyed the British government and has killed or otherwise incapacitated both the Prime Minister and the "second person" (normally a high-ranking member of the Cabinet) whom the Prime Minister has designated to make a decision on how to act in the event of the Prime Minister's death.
 In the event that the orders were to be carried out, the action taken could be the last official act of Her Majesty's Government.
The Swedish constitution of 1974 allows the Prime Minister of Sweden to appoint one of the Ministers in the cabinet as Deputy Prime Minister ("biträdande statsminister", also unofficially known as "vice statsminister", "Vice Prime Minister"), in case the Prime Minister for some reason is prevented from performing his or her duties.
 However, if a Deputy Prime Minister has not been appointed, the Minister in the cabinet who has served the longest time (and if there are several with equal experience the one who is oldest) takes over as head of government.
 Note that the person acting as Prime Minister does not do so on a permanent basis: if a Prime Minister dies, resigns or loses a vote of confidence in the Riksdag, the Speaker of the Riksdag will then confer with the parties of the Riksdag and propose a new Prime Minister, who must be tolerated by a majority of the Riksdag.
 If the Prime Minister has resigned or lost a vote of confidence, he or she will remain the head of a government "ad interim" until the new Prime Minister assumes his or her office.
 The only case where the governmental line of succession becomes relevant is when the Prime Minister dies (upon which the person next in the line of succession serves as the head of a government "ad interim") or when the Prime Minister is on leave or for any other reason incapable of serving, but still remains in office.
 This might be compared to the Presidential line of succession in the United States, where the person next in line assumes the Presidency throughout the remainder of the term if the President dies, resigns or is impeached.
