The UK will ultimately give ground on it, of course, because rules on state aid don't really mean anything. Basically what happens under such rules is that you have a company that is struggling, so you give it state money to help it out. Then the EU gets angry and mounts a legal challenge. After several months / years the EU wins, you apologise, and the money is returned. In the meantime the company was either viable, has been saved by the loan of the cash, and can return it happily, or it wasn't viable and is allowed to fail.
It's a trick our good friends the French use time and time again to great effect, and we have all become more European and will act accordingly
