UK prime minister, Boris Johnson has lost his majority of one after Tory MP Philip Lee defected to the Lib Dems by sitting on their bench.
Metro reports that he made the move while Boris Johnson was mid-way through delivering a speech in the House of Commons.
The surprise move means there is now no parliamentary majority.
The MP crossed the floor ahead of a crucial vote tonight in which rebel MPs will try to take control of the Parliamentary agenda and block a no-deal.
In a letter of explanation, the MP for Bracknell said it was ‘no longer possible to serve my constituents’ and the country’s best interests as a Conservative Member of Parliament. He said he believed the Liberal Democrats were the best party to build a ‘unifying and inspiring political force’
