Justice Secretary Chris Grayling has weighed into the row over why John Bercow gave a parliamentary pass to a woman funding his re-election campaign. Responding to a question from Guido at his press conference this morning, Grayling warned:

“It’s certainly the case that passes to the House of Commons should not be given out lightly. They can only be given out to people who have a proper reason to be there. Any Member of Parliament, and obviously the Speaker of the House of Commons is a Member of Parliament like the rest of us, who has issued a pass to a third party, must have a good reason for doing so. And if they don’t have a good reason for doing so they will undoubtedly face questions from a great number of people as to why that is the case.”
