I don’t think that Johnson has a choice tbh.
They must go for some sort of deal and if you break it down, I think that the U.K. will actually benefit from accepting the deal.
State aid - the U.K. has never been as generous as other EU countries in supporting their businesses, so in fact it would benefit the U.K. if state support is held at a certain level.
Level playing field - this provides certainty to U.K. business with the knowledge that they are competing in a fair field
Fisheries - the issue is undoubtedly something that is going to be very difficult both to us and France. However, if we allow this issue to scupper the deal, which would mean destroying our farmers, how would that make any sense? Fishing would still be trading , the6 would have a bigger % of the fish available and we would save our farmers. I think it is a no brainier.
