What will come out of this week's "super Saturday" sitting?

David Miliband: Firstly, please, let's never again use the phrase "super Saturday" to describe a sitting of Parliament. If it's a national emergency for us to meet on a Saturday, it can hardly be super. Now, we do not yet know whether or not Parliament will meet. If it does, it probably means that the Prime Minister, Boris Johnson, has got a deal with the European Union and wants to have it ratified.
