On Monday, John Bercow told the government that it cannot send Theresa May’s Brexit deal back for a third vote in parliament immediately unless substantial changes are made to it.

His argument is based on Erskine May - the rules of the house. Some people who don't like the ruling say it's based on an ancient 17th century rule. As if that puts it  into the category of one being fined sixpence for not doing one's archery practice once a week. The point is that a rule that has stood the test of time is a good rule and has been used to guide parliamentary procedure for over 300 years.

No "best of five" for May.

Which highlights the need for somebody to ask why we can't have a Second Referendum now we know all the facts.
