- When David Cameron refused to agree to some of Nick Clegg's limited House of Lords reforms he lost the Lib Dem support for the implimentation of the electoral boundaries review. This would have handed the Tories another 30 or more seats.
- Had he gone along with it that would have given the Conservatives a majority of 47 or more in the 2015 election.
-Even if he'd still jumped over the side of the ship in 2016 maybe Mrs May would not have been so tempted to call another General Election in 2017.
Dave , it seems, doesn't have sums as one of his stronger points.
