NICOLA Sturgeon has said that the Prime Minister's bid to re-open her Withdrawal Agreement "highly irresponsible", adding the the plan is "doomed to failure".

She sent the tweet accompanied by a thread by Robert Peston.

The First Minister tweeted: "This thread sums up the situation well. PM surely can’t be allowed to continue down a track that might avoid defeat at hands of ERG today but is ultimately doomed to failure – and which therefore increases the chance of no deal.

"It is highly irresponsible."

MPs are currently debating Theresa May's plan B in the House of Commons ahead of a debate and vote on seven amendments. They will then vote on May's plan B.

The Prime Minister appealed for MPs to "send an emphatic message" about the Brexit deal they wanted.

She said she accepted her plan had been defeated: "The vote was decisive and I listened, so the world knows what this House does not want.

"Today we need to send an emphatic message about what we do want.

"I believe that must include honouring the votes of our fellow citizens and completing the democratic process that began when this House voted overwhelmingly to hold the referendum, then voted to trigger Article 50, and which saw the vast majority of us elected on manifestos pledging to see Brexit through."
