EU referendum, brexit and the aftermath

Just read the farming one. Seems that nothing is (will be) changing legislation-wise as the U.K. would conduct the subsidy process in the same way.

I don't know the answer to this, but I wonder if they sign a new deal with someone around (for example) farming, are state subsidy levels up for grabs in that? I mean, would the terms of the deal be altered depending on the level of subsidies that farmers are provided with (as the UK farmers receiving govt subsidies places gives them at an unfair advantage over the second countries farmers).

I wonder which the Tories would be prepared to sacrifice first - the new trade deal or the EU level farm subsidies.
