A health minister faces calls to resign after he warned that leaving the EU is a terrible mistake.

Lord Prior of Brampton, who is the first Remain supporting minister to publicly criticise Britain’s decision to leave the EU, has been told by his colleagues that he should step down if he “can’t cope” with Britain’s decision.

At a dinner of the Royal College of Physicians, he said that the government must "do everything we can" to keep market access and attract qualified people from overseas.
