As Jim said, completely inevitable after hard Brexit looks likely. In fact, I don't see how the Scottish govt could have avoided it. Polls are showing 48-50% yes, so that is more than last time.
I had to laugh at Labour's reaction, of course, they are going to oppose it, to save Kezia's face, but it makes them look daft.
The basic principle of the self-determination of nations makes me say, vote yes.
