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.
