On the contentious and topical subject of what constitutes a mandate for a second independence referendum, we’re grateful to the super-alert reader who unearthed this clip from BBC Scotland’s election night coverage of 2011, in which Ruth Davidson gives a candid and blunt explanation of the criteria required:

We’re just going to write that one down for the record.

“You don’t get a referendum for free, you have to earn it. So if the Greens and the SNP – and the SSP or any of the other parties who’ve declared an interest in independence – get over the line and can make a coalition, make a majority, get the votes in the Parliament, then they’ll vote through a referendum, and that’s what democracy’s all about… it’s perfectly simple”

We’d have to say that that sounds pretty unambiguous to us – if you’ve got the votes for it in Parliament you get to do it, no matter what anyone else thinks or what anyone says. We welcome and sincerely salute Ms Davidson’s unqualified commitment to the principles of Parliamentary democracy.
