What record does Sir John Major hold since the death of Margaret Thatcher at the age of 87?
John Major Sir John Major, {'1': ", '2': ", '3': ", '4': "} (born 29 March 1943) is a British politician who was Prime Minister of the United Kingdom and Leader of the Conservative Party from 1990 to 1997. He served as Foreign Secretary and then Chancellor of the Exchequer in the Thatcher Government from 1989 to 1990, and was the Member of Parliament (MP) for Huntingdon from 1979 until he retired in 2001. Since Margaret Thatcher's death in 2013, he is the oldest living former Prime Minister.
Michael Portillo Michael Denzil Xavier Portillo PC (born 26 May 1953) is a British journalist, broadcaster, and former Member of Parliament and Cabinet Minister. He was first elected to the House of Commons in a by-election in 1984. A strong admirer of Margaret Thatcher, and a Eurosceptic, Portillo served as a junior minister under both Thatcher and John Major, before entering the cabinet in 1992. A "darling of the right", he was seen as a likely challenger to Major during the 1995 Conservative leadership election, but stayed loyal. As Defence Secretary, he pressed for a purist Thatcherite course of "clear blue water", separating the policies of the Conservatives from Labour.
