The first half is excellent. Trapped in a Spanish airport by the Icelandic ash cloud, three young politicos are forced into a road trip adventure to make it back in time for the election result. Martin Hutson is a Labour special advisor, Charlotte Lucas is a Lib Dem staffer and Jamie Glover is a Tory MP licking his wounds after the expenses scandal and there’s huge fun as they thrash out the various permutations of a hung parliament and what that would mean for politics in the UK. It’s wordy but funny, Edgar disguises strategising with a little comedy and comes up a plausible, Thick-of-It-style version of what could well have happened involving camels (funnier and cleverer than it sounds).
