An interesting little exchange here between Conservative former Scotland minister Lord (Michael) Forsyth and the BBC's Scotland political editor Glenn Campbell:
Lord Forsyth: How can Glen Campbell (BBC) say we learned nothing new. We listened for nearly 6 hours to a measured account backed with documentary evidence of how Alex Salmond came to make his devastating charges against the Scottish Government and the committee struggled to challenge him.
Glenn Campbell: Because I have followed closely all the written evidence submitted in advance. That is not to say that Alex Salmond did not articulate his case well - he certainly did.
Levi Stubbs: I learned loads. This isn't about Glenn Campbell learning something new. It's about the public learning something new.
