Crossing the floor of the Scottish Parliament – moving around the arc is perhaps a better description – is highly unusual.

Jamie Greene is a one-time Scottish Tory leadership contender who resigned the Conservative whip with an excoriating letter to his leader Russell Findlay on Thursday. The very next day, the ex-Tory turned up at the Scottish Liberal Democrat annual conference in Inverness to announce he would be joining the party. It was a genuinely significant Holyrood moment.
More importantly, though, it looks to be a genuinely significant moment in the fortunes of the Scottish Tory party.
