Labour shadow foreign secretary Emily Thornberry took a swipe at Theresa May yesterday, warning that she didn’t “have enough authority” to lead Britain through the Brexit process.

Ms Thornberry made the comments on Sky News after the PM suspended two rebel Tory MEPs who behaved “totally irresponsibly,” according to a government source.

Ms May withdrew the party whip from South West MEP Julie Girling and South East MEP Richard Ashworth after they supported a resolution in Strasbourg declaring that “sufficient progress” had not been made in the Brexit talks to be able to move on to discussions about a future partnership.
