Brexit Secretary Stephen Barclay said that Speaker of the House John Bercow had caused more uncertainty after allowing the ‘Plan B’ vote to go ahead last week.
He told the BBC’s Andrew Marr Show: “There are lots of different plans being put forward by MPs that don’t respect the (referendum) result or risk no deal.”
Barclay said that Brexiteers seeking ‘ideological purity’ by voting the Prime Minister’s deal down were ‘leaving the door ajar to ways that increase the risk to Brexit.’
He declined to say if the Government had a plan B but added that he believed the Commons would eventually support a version of May’s exit deal.
Also on the Marr Show, Labour leader Corbyn said his MPs would vote against the deal and seek a General Election if May lost.
He said: “We will table a motion of no confidence in the government at a time of our choosing, but it’s going to be soon, don’t worry about it.”
Corbyn is under increasing pressure from a growing number of his own MPs and party members to come out in support of a second EU referendum.
But he told Marr that he would prefer a General Election first and the priority was to ensure the UK did not crash out of the EU without a deal.
“My own view is that I’d rather get a negotiated deal now, if we can, to stop the danger of a no-deal exit from the EU on 29 March – which would be catastrophic for industry.”
If MPs support a no confidence motion the government – or any other grouping – will have 14 days to win another confidence vote – if not a general election will be held.
