British Foreign Secretary (foreign minister) Boris Johnson strongly criticized Prime Minister Theresa May's latest Brexit proposal in typically colorful terms before agreeing with his colleagues to back the compromise Friday, reports said.

Johnson, a leading supporter of a decisive break by Britain from the European Union, said May's "business-friendly" plan was a "big turd" that would need to be "polished" in order to be sold to the public, the BBC said.

Johnson made his comments during eight hours of talks at May's country residence that ended with the Cabinet, including himself, signing up to the plan.
