Past UK Conservative leaders who faced leadership challenges


              Former British Prime Minister, Margaret Thatcher, leaves 10 Downing Street, in London, Monday, Nov. 23, 2009. British Prime Minister Boris Johnson may have survived a no-confidence vote, but his grip on power is far from secure. Many compare his position to that of his predecessor Theresa May, who won a similar vote by a larger margin than Johnson but was nonetheless ousted six months later. Further back in time, Margaret Thatcher survived a first leadership challenge in 1989, but a second one the next year spelled her downfall. (AP Photo/Sang Tan)

British Prime Minister Boris Johnson may have survived a no-confidence vote, but his grip on power is far from secure. Major took over as Margaret Thatcher’s handpicked successor in December 1990. In June 1995, Major resigned as party leader to force a leadership contest against himself, challenging his party to “put up or shut up” in a bid to quell a persistent group of critics within the Conservative ranks opposed to Britain’s closer integration with the EU.
