The Prime Minister had vowed to leave the EU without a deal if the two sides failed to thrash out trade terms by an October 15 deadline. But negotiations are rumbling on with less than five weeks to go before the Brexit transition expires and Mr Redwood said the time had come to get out.
The senior Tory MP tweeted: “The Prime Minister promised us we could just leave the EU if there was no deal by October 15th. Time to deliver the promise.”
His views were welcomed by Brexiteers on social media.
One supporter tweeted: “What was the point of gaining an 80 seat majority if you’re not prepared to use it? Walk away Boris Johnson and give us some pride back.”
Another said: “It is time to go. We cannot carry on like this any longer. The uncertainty is not good for the British people.
“Boris should not continue this ridiculous behaviour into December.”
The calls to quite immediately come as EU chief negotiator Michel Barnier heads to London in a last-ditch attempt to clinch a Brexit trade deal.
Both sides are calling on the other to move their positions on fishing rights and competition policy to clear the way for a trade deal that would avoid a tumultuous finale to the five-year Brexit crisis.
Face-to-face negotiations will resume after they had to be suspended last week when one of Mr Barnier’s team tested positive coronavirus.
Mr Barnier said: “In line with Belgian rules, my team and I are no longer in quarantine.
“Physical negotiations can continue. Travelling to London this evening to continue talks.”
Downing Street insisted the Government remained committed to securing a trade deal.
The Prime Minister’s official spokesman said the UK side was “committed to working hard” to reach a free-trade agreement and were working to “bridge the gaps that remain between us”.
He said: “Throughout the negotiation, our position has been consistently clear.”
