The Speaker of the Commons gets asked a point of information about the possibility of Trump speaking at Westminster Hall. Speaker Bercow left no doubts about his view on that. As Dennis Skinner says at the end “Just two words, Mr Speaker. Well done.”
However since this happened Bercow is facing calls for him to resign. These calls come from Tory MPs. So no surprise there. The grounds for a resignation are said to be the Speakers make an agreement to be politically neutral while they hold the position of Speaker.
You might say that Bercow’s words were not political neutral in that they go against the stated views of the PM in inviting him for a Royal State Visit as opposed to a Head Of Government visit. I prefer to think of Bercow giving the Commons the ethical argument for why Trump should get nowhere near Westminster Hall or the Royal Gallery.
