A new trade deal with the European Union worth billions to the UK economy must be a “launch pad” for reversing Brexit, Andy Burnham has been warned.

The prime minister is set to unveil a deal with Brussels at the end of the month worth 0.4 per cent of the UK GDP, which will see border checks on food and drink stripped away, a new youth mobility scheme and a much closer working partnership with the bloc.

He has set out to be bolder than his predecessor, Sir Keir Starmer, but has maintained Labour’s manifesto red lines, which prevent agreements on free movement, or rejoining the EU, customs union or single market.

Instead, he plans to use the summit in Brussels on 20 November to launch a new discussion on the options for the UK beyond the next election, with rejoining the bloc on the cards as a manifesto pledge.
