Carrying on the state aid conversation from anotehr thread here instead
The EU, or let's call a spade a spade and just say 'Germany', really hates state aid. They took Greece to court for bailing out their shipyards, and attempted to do likewise with Spain. They won't need to bother taking us to court, they can just say 'deal's off, have fun starving to death'.
And the Tories aren't exactly massive fans either, and what with just having come very close (in 2017 at least) to a Corbyn government that had nationalisation at the heart of its manifesto its hard to imagine where the incentive would come for this cabinet to fight for that particular change in the relationship with the EU. Its just the kind of issue they'd be happy to back down on in the hope of getting something they actually want. Any words from the Tories that claim they really want rid of state aid rules are most likely positioning for future horse trading.
For example yesterdays FT suggests a big fight over state aid - especially as BJ has supposedly been making sounds that are designed to signal (to the public) that he wants the state to Buy British etc
Red line on subsidies sets tone for the trade battle to come

however they key bit is " British officials have insisted that Mr Johnson does not envisage a big increase in state aid after Brexit, rather that he wants to be able to intervene more promptly; they cite attempts by the government to help the UK steel industry in 2015, which they claim were hindered by a “50 day” wait for state aid approval from Brussels. " (in fact they used it as cover not to have to act)
Some other bits from that article
" if Britain is able to use public money to bolster key companies in a way that EU countries are not, it will give UK businesses a competitive advantage — something Brussels is determined to prevent."
and
" The sensitivities around state aid are heightened by the concessions that Britain had to make on the issue when it hammered out a Brexit deal with the EU. A core part of arrangements for preventing a hard border on the island of Ireland is that Northern Ireland must stay within the EU’s state-aid regime. EU officials note that in practice this means the UK will need to notify state-aid decisions for review by Brussels — even if they only have indirect relevance for Northern Ireland. Making that system mesh with the broader state-aid conditions attached to a trade deal will be fiendishly difficult."
Finishes to say EU holds all the cards and the UKs self imposed deadline means the game of chicken is one the UK government is more readily going to lose. So yeah, Id say the odds of seeing state aid rules being binned is very unlikely-to-zero
