Off the record
We've been trying to find out more about the story that Gordon Brown and Sir Menzies Campbell have held private talks about a plan for one or two senior Lib Dems to join Mr Brown's first cabinet. I've been talking to my "contacts" within the party, people I've talked to for years, ever since I spent the 1997 election campaign travelling around with Paddy Ashdown on his big yellow bus.
The frustrating thing is that so many of them have fascinating information and insights, but feel reluctant to talk publicly about what is going on - of course there's a sense of brinkmanship going on here. They don't want to give the impression that they are gagging for what Ashdown called " a bum in a ministerial Rover" but nor do they want to seem unco-operative when it comes to talking about future talks on the constitution for example. Some insiders can't stand the idea of linking up with Labour - if other parties need us, they say, then those parties should come to us. It's at moments like this that I envy my colleagues in the newspapers who can write up comments without naming the contributor.
As I write though we've just booked the Lib Dems' Home Affairs spokesman Nick Clegg for an interview. Not that he said any of the above privately to me, I have to stress.
