How many policies has David Cameron got?

Having had his education policy half-inched by the Labour party, Cameron now seems to have had another of his key ideas nicked. The Chancellor slipped this little snippet into his speech today:

There will be a new community youth service to help fund gap year students doing voluntary work in the UK.

Which sounds awfully like the national service idea espoused by DC. I have no problem with Labour pinching good Tory ideas. But who is the bigger plonker here - the plonker who thinks up a daft idea or the plonker who pinches it from him?
