Primary data is fact
agreeing to "single market" legislation though is a long way from the current ceding of power and quite an acceptable position.
The majority of legislation is related to the single market, leaving this to a body (ie the EU) where there is no UK goverment input seems unwise to me; it most certainly is not just a series of individual trade deals.
Besides, you need two parties for an agreement and I think it quite possible that the EU would not see concluding bilateral arrangements with the UK as a priority, or even desirable.
