Another UK minister quits in protest at PM May’s Brexit deal

British science and universities minister, Sam Gyimah, quit Prime Minister Theresa May’s government on Friday, the sixth minister to resign in protest of her proposed Brexit deal with the European Union.

Gyimah, a junior-ranking minister who campaigned in the 2016 vote to keep Britain in the EU, said May’s deal meant Britain would surrender its “voice and its veto” and that the prime minister should not rule out the prospect of a second referendum.

His resignation represents a further blow to May, who is trying to persuade her own lawmakers to approve the deal she struck with Brussels on Sunday.

May faces criticism from all sides including the Northern Irish party propping up her government, ahead of Britain’s departure from the EU in four months.
