The variable cost of Cornwall's MPs

As you might expect, today's publication of MPs' expenses claims provides hacks like me with endless opportunities for harmless fun. Here are the headlines:

Sheryll Murray - £15,755.12
Stephen Gilbert - £7,619.93
Dan Rogerson - £5,095.07
Andrew George - £4,339.27
Sarah Newton - £3,877.50
George Eustice - £498.86

So why was Sheryll 32 times as expensive as George? Good question. No doubt more details in due course.
