John Major's intervention through the pages of the Telegraph urging Labour to rule out a post election pact with the SNP demonstrates just how much the UK political landscape has changed recently. Many Scots are burdened with a grievance at the outcome of the referendum (cynics may comment that many Scots are always burdened with a grievance and that it is never difficult to distinguish between a ray of Sunshine and one such) and no doubt many will paint themselves in woad and wear kilts of ancient clans to which they may or may not belong as May approaches in order to demonstrate their allegiances.
In England, the Greens have become the insurgent party of the young and unfulfilled - all those young people with useless degrees from third-rate educational institutions who in years past would have made perfectly adequate hairdressers or clerks without the burden of tens of thousands of student debt. UKIP of course are the insurgent party of my own Alzheimer generation, fearing mental decline and the loss of national character in equal part. And some people may even vote Liberal Democrat.
All of this means that there are no 'constitutional conventions' to apply as the intense electioneering approaches. Whether this election of many parties is the harbinger of future multi-party politics or a one-off remains to be seen. What's certain is the result is more uncertain than at any time in my life. And that's actually a good thing.
