What British Prime Minister committed the British Conservative Party to supporting Scottish devolution through the Declaration of Perth?
Edward Heath Sir Edward Richard George Heath, (9 July 1916 – 17 July 2005), better known as Ted Heath, was a British politician who served as Prime Minister of the United Kingdom from 1970 to 1974 and Leader of the Conservative Party from 1965 to 1975. He was a strong supporter of the European Communities (EC), and after winning the decisive vote in the House of Commons by 336 to 244, he led the negotiations that culminated in Britain's entry into the EC on 1 January 1973. It was, says biographer John Campbell, "Heath's finest hour". Although he planned to be an innovator as Prime Minister, his government foundered on economic difficulties, including high inflation and major strikes. He became an embittered opponent of Margaret Thatcher, who supplanted him as party leader in 1975.
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.
