Nick Boles, author of Which Way's Up?, featured on the BBC's Today programme this morning.

He discussed how David Cameron and Nick Clegg should bind their parties into an electoral pact by the end of the year and warns that unless the two parties form a ten year-programme for the government, MPs will look to "bolt" from the coalition when they are faced with the electoral consequences of its "harsh but necessary measures".
