Labour will try to keep the UK in the single market and customs union after Brexit, the party’s shadow Brexit Secretary has announced.

Sir Keir Starmer has outlined his intention to try and derail the Government’s EU Withdrawal Bill - dubbed the Repeal Bill - by proposing an amendment to keep existing trading arrangements with the bloc during any transitional period.

His plan further confuses Labour’s Brexit policy and appears to contradict Jeremy Corbyn’s statement that under his leadership the UK would leave the single market.

Sir Keir’s plan will seek to take advantage of Theresa May’s failure to win an outright majority at the general election by setting out a way forward which could win over pro-European Tory MPs.
