A British government minister has quit his post in protest against Theresa May’s announcement that she will request yet another Brexit delay to give her time to seek a compromise with the opposition Labour Party. Nigel Adams is the first minister to quit following Tuesday’s cabinet meeting, leaving his roles as a junior minister and quitting as an assistant Conservative party whip. In his resignation letter, posted to Twitter, Adams said May’s decision to delay Brexit again and ask for Jeremy Corbyn’s help was “a grave error” and predicted she would now pursue a much softer form of Brexit. “It now seems that you and your cabinet have decided that a deal—cooked up with a Marxist who has never once in his political life put British interests first—is better than no deal,” he wrote. May will meet the left-wing Labour leader on Wednesday in an attempt to find some common ground. Corbyn has previously said he wants a customs union with the EU. Meanwhile, the British Army has launched a full investigation after footage emerged showing troops using a picture of Corbyn for target practice.
