I'd disagree about 'their main objective', though it would certainly have been high on any list of goals!Their intrangency on those three priorities were a deliberate ploy to hold up trade talks and stiffle a chance of reaching a suitable agreement for the UK. This was done to push a stinker of a WA along with their main objective of keeping the UK in the EU.
I'm pretty certain that their Main Priority was/is to create significant 'disincentive' for other members who might consider leaving. And for this reason, I expect the EU to take a very hard line in any future negotiations - even though such an attitude might be to the detriment of member states!
