We reserve judgment on the content until we hear what she has to say, but the indications are that Theresa May’s message tomorrow will be that she can deliver a Brexit settlement which works for Scotland.
If she can indeed, this would go some way towards keeping the referendum wolf from her door, but it is hard to see how she can convince on this matter anytime soon, when she is determined not to show her hand.
We should remember that an independence referendum is not unavoidable. In fact, an acceptable Brexit settlement may just get Nicola Sturgeon out of a hole as well.
But it’s up to May to demonstrate she means what she says, and can deliver.
