Josip Manolić (] ; born 22 March 1920) is a Croatian politician and former high-ranking official of the State Security Administration (UDBA or UDSA) who was the Prime Minister of Croatia from 24 August 1990 to 17 July 1991.
 Croatia formally declared independence during his term, on 25 June 1991.
 Having taken office as Prime Minister at the age of 70 and having left the office at the age of 71, he is the oldest person to date to have served as Prime Minister of Croatia.
 Manolić is also the oldest currently living former prime minister at the age of and the longest-lived holder of the office.
 Following his brief term as Prime Minister he served as the first Speaker of the Chamber of Counties, the upper house of the Croatian Parliament, from 1993 until 1994.
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 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.
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.
