Exclusive: Oaten writing coalition manual for Lib Dems?

It looks like the Liberal Democrats' recent interests in coalition government is growing. The MP for Winchester, Mark Oaten, is apparently spending the remaining days on his taxpayer-funded salary writing a book about the subject rather than serving his constituents.

This has involved him writing to a number of think-tanks on House of Commons paper asking for any work they may have done on the topic, and letting them know he’d like to chat with them. Presumably he's angling for an invitation to speak.
