Guy Verhofstadt has sent a warning to the Prime Minister of Brexit talks.

The senior EU boss warned Theresa may that she would be ‘sabotaging’ the negotiations if the government is unable to provide an Irish border solution.

Verhofstadt said: “The UK Government can no longer postpone coming forward with its own workable and legally operative proposal for a backstop,” he said.

“We have yet to see a legislative proposal from the UK Government, despite repeated commitments made by the Prime Minister.”

Adding: “Any suggestion that the UK Government will renege on the commitments it has already made only risk to undermine trust and sabotage negotiations.”

Theresa May forced Dominic Raab, the newly appointed Brexit secretary aside as she made the decision to take full control of the Brexit talks, despite voting remain and not publically coming out in support for the UK leaving the European Union.

The Prime Minister chequers plan was smacked down by Michel Barnier this week over the governments plan to collect tax on goods for the European Union.

Mr Barnier said: “The EU cannot, and the EU will not, delegate the application of its customs policy and rules and VAT and excises duty collection to a non-member who would not be subject to the EU’s governance structures.”
