Treaty on the Functioning of the EU

I very much welcome the Government’s decision to opt out en masse and then decide item by item on whether to opt back in, which I see as a rejection of ever closer union, but how will we deal with the matters post negotiation? If there are 35 items that the Government propose to opt back into, will we vote item by item, because the Government might well succeed in their objectives in some of them but not in others? Rather than simply having a vote on a lump, would it not be much better to give us individual choices, and would that not also strengthen the Home Secretary’s position?
