Boris Johnson's brother resigns as junior transport minister

Jo Johnson, the brother of leading Brexit campaigner Boris Johnson, resigned as a junior transport minister on Friday, issuing a damning critique of Prime Minister Theresa May's "delusional" Brexit negotiation and calling for a vote on her final deal.

"Britain stands on the brink of the greatest crisis since the Second World War," Johnson, who voted to stay in the EU in the 2016 referendum, said in a statement.

"Given that the reality of Brexit has turned out to be so far from what was once promised, the democratic thing to do is to give the public the final say," he added.
