WATCH: Dominic Grieve says he 'has never been more ashamed to be a Tory' in furious blast at Theresa May
Dominic Grieve has said he has “never been more ashamed” to be a Conservative after Theresa May claimed that MPs are to blame for the Brexit stalemate.
In a scathing attack, the former Attorney General said watching Mrs May's barbs at the backbenches during Prime Minister's Questions was his "worst moment".
His comments, in an emergency Brexit debate, came after the Prime Minister confirmed that she had asked EU Council president Donald Tusk for an extension to Article 50 until 30 June.
Mrs May slammed MPs as having "indulged themselves on Europe for too long" as she called on MPs to finally back her withdrawal agreement.
She added that it was “time for this House to determine that it will deliver on Brexit for the British people”.
But Mr Grieve later told the Commons that he "could have wept" at his colleague "castigating the House".
"When the Prine Minister came to despatch box today at Prime Minister's Questions I confessed I think it was the worst moment I have experienced since I came into the House of Commons," he said.
"I have never felt more ashamed to be a member of the Conservative Party or to be asked to lent her support.
"She spent most of her time castigating the House for its misconduct and at no stage did she pause to consider whether it is in fact the way she is leading this Government which might be contributing to this situation."
Mr Grieve added that he had "great sympathy" for the PM in her position but added: "I have to say I could have wept. Wept to see her reduced to these straits and to the extent she was zig zagging all over the place rather than standing up for what the national interest must be."
