UK Prime Minister suffered an unprecedented defeat on Tuesday, on the first of five days of Brexit debates ahead of a crucial vote on the withdrawal deal next week.
MPs found May’s government in contempt of parliament for refusing to release its full legal advice on Brexit, in a motion which was backed by 311 to 293 and ordered the immediate publication of the advice.
The move was backed by six opposition parties and the DUP, whose votes are crucial for May’s governing majority.
Responding to the result, Leader of the House of Commons Andrea Leadsom said the government will publish the full legal Brexit advice on Wednesday.
During the debates, ex-foreign secretary Boris Johnson dismissed May’s plan for the UK’s future relationship with the EU as a “paint and plaster pseudo-Brexit.”
“This isn’t Brexit, this is not Brexit, but a feeble simulacrum of national independence,” he said.
MPs will vote whether to reject the terms of the UK’s withdrawal and future relations with the EU next Tuesday, 11 December.
