Iain Dale's Telegraph column is definitely going to be controversial. Here's a small extract:
[Tories should pledge a vote on being in the EU.
Stealing other parties' policies is almost de rigueur for politicians nowadays. Gordon Brown is the busiest magpie of all: none the less I suggest that David Cameron looks to the Lib Dems to steal a policy that might mean the difference between being the largest party in a hung parliament and being prime minister of a government with a Conservative majority.]
This is going to be a very hot topic over the next couple of days. A brave move by Mr Dale.
ConservativeHome disagree with Iain, feeling that it isn't a simplistic question of in-or-out.
