Someone has started a bit of a book crossing thing in one of the rooms at work. I found this - I've never seen it anywhere else.
A short story is that thing's are not going well, so the Prime Minister takes a short break and goes undercover travelling around the country in cognito accompanied by a policeman.
Very obvious parody of New Labour - possibly a bit too obvious, but still a good fun read with some very funny bits in it (the MI5 guys listening in). It was also surprisingly affectionate. The prime minister wasn't completely loathsome - I think the point was slightly that you'd have to be a bit mad to want to run a country.
I was slightly disappointed with the ending on first reading, but like a couple of other books I've read this year, it seemed better after it had sunk in for a few hours.
