You asked for a Plan B...
If you listen to the Scottish FM she is clear that the Scottish Government would be OK at the moment with a UK Leave deal that included tariff free access to the Single Market. She has been asked a lot of times in the last couple of days whether she'd retract her call for Indyref2 if May walked back her Lancaster House statement on the UK will be leaving the Single Market. Her reply has been that May has shown absolutely no indication whatsoever that that is a possibility.
Good Plan B - Hedge bets and see what the UK Government walk away with. Nether you nor I know what is going to be negotiated, perhaps the EU might suggest a deal that gives the UK access but it is not for our Government to suggest it as we (that's all of us) are down to leave.
