British lawmaker Oliver Letwin said on Saturday it was not responsible for Prime Minister Boris Johnson to threaten a choice between his Brexit deal and a no deal. Letwin has put forward a proposal which is due to be voted on later on Saturday to withhold support for Johnson’s Brexit deal until formal ratification legislation has passed. “The prime minister has a strategy … he wants to be able to say to any waverers ‘it is my deal or no deal, vote for the implementing legislation or we crash out’,” Letwin told parliament.
