Sundays are about to get a lot rowdier, at least when it comes to political discussion and analysis. Robert Peston's move to ITV was a coup for the broadcaster, and the news that he might be going up against Andrew Marr's Sunday show set Twitter clucking.

Some people watch sport at the weekend. Some of us have this.
