Sir Keir Starmer has said he does not see the UK rejoining the European single market or customs union in his lifetime.

Speaking to reporters on the campaign trail in Carmarthen, he added: “I’ve been really clear about not rejoining the EU, the single market, or the customs union, or returning to freedom of movement.
