Labour's Toby Perkins says he'd like officials to be sent back to the negotiating table.
Theresa May has spent three hours defending her Brexit deal in the House of Commons, but many MPs remain unimpressed, including the Labour MP for Chesterfield Toby Perkins.
He's welcomed the customs arrangement included in it, but found little else to cheer about in the lengthy document published last night.
Mr Perkins believes the government should go back to the negotiating table, taking with them constructive suggestions from MPs.
The Prime Minister has today been hit with a string of ministerial resignations, and there are growing calls for a challenge to her leadership of the party.
Mr Perkins has told us it's 'clear' Theresa May is unable to lead her party, but added he doesn't feel anyone else is up to the job either, saying he isn't sure the Conservative Party is 'capable of being led' at the moment.
He's calling for a general election to be held, and admitted the case for a second Brexit referendum, known as a 'People's Vote', is 'becoming compelling'.
