1. Free movement is not up for discussion, pointless to even try.
2. Seems to be support for this elsewhere, will not be anywhere near what some euro sceptics want.
3.Pretty sure this power already exists...
4. 'Cut red tape' doesn't really mean anything, if he means things like WTD ( which UK ignores anyway afaik) then he wont get much movement.
5. Nothing to do with EU, seems strange for him to even propose it.
6. Might get some support in countries with high anti-EU elements, don't think he'll get unanimous agreement though.
7. Founding principal of the EU, not up for discussion.
So instead of trying to actually affect significant reform he has chosen to pick areas which are not up for discussion, where he cant win in an attempt to placate his backbenchers / deflect attention from UKIP... Typical Cameron to be fair.
