Keir Starmer was last night warned he would betray Brexit if he agreed a deal that put the UK back under the control of the EU.

The Prime Minister is today set to sign an agreement at what has been dubbed his ‘Surrender Summit’ that will mean Britain must once more follow EU laws and abide by its judges’ rulings.

He is also poised to hand millions of young Europeans the right to live, study and work here for up to three years, risking his pledge to cut migration. And the PM – who backed Remain then campaigned for a second referendum to undo the Leave vote – is expected to ‘sell out’ Britain’s fishermen by allowing French boats continued access to UK coastal waters.

Talks were going down to the wire last night after the EU made surprise 11th-hour demands for the fishing rights to last a decade or more. In return, checks on lorries taking food to the continent would be lifted. Defence firms will gain access to a £126 billion EU-wide weapons fund – but British taxpayers face having to pay millions for the privilege.

As the wrangling continued over the ‘reset’ deal to be unveiled at London’s Lancaster House, the PM was urged not to give in to the EU’s demands or give up the Brexit freedoms that 17.4 million voted for.
