More than twice as many people want to scrap Britain’s commitment to spend 0.7 per cent of GDP on foreign aid then keep it, a new poll has found as Tory MPs demanded a review after the Brexit vote.

Seven in 10 Britons want to see the promise gone while just 30 per cent want it to remain in place, an exclusive ORB poll for this newspaper has found when undecideds are removed.

It came as Tory MPs demanded a review of the pledge now that Britain will be free to set up trade deals with developing countries after leaving the EU.
