Theresa May has two clear options on Brexit – neither of them easy

David Cameron has indicated that he will resign as British Prime Minister on 13 July, with Theresa May due to take over following her victory in the Conservative Party leadership contest. Gavin Barrett writes that the new Prime Minister will be faced with an exceptional challenge in handling the fallout from the EU referendum. He suggests that any attempt to rerun the vote would be problematic, but that it is highly unlikely she will be able to secure a deal that restricts EU free movement of persons while retaining access to the single market.
