You're correct. Though I think as sinsofsolarempirefan pointed it, it may be advantageous for England+Wales and for the Tory party to do so

Though now I just remembered - isn't the Tory party full name the Conservative and Unionist party?

[sinsofsolarempirefan]

Yes, it is the Tory and Unionist party. Maintaining the Union is an inherent part of the Party’s ideology. During the indyref debate Scottish members of the party were expelled from the party if they campaigned or admitted to voting for independence. It is one of their core tenets. This is despite the fact that it would be politically beneficial to the Tories to see Scotland leave and economically beneficial for England and Wales (and NI too, if they decided to stay).
