When I was young, it was Labour whose enthusiasm for intra-party punch-ups helped keep it out of power for eighteen years.

As a teenager, I watched agog as Neil Kinnock was heckled live on television, begging his party to end what he called it’s ‘grotesque chaos’. It was unthinkable that the Conservatives might ever rip themselves apart in a similar fashion.

And yet here we are.

The Chancellor’s so-called ‘Punishment Budget’ in which he’s threatened to raise tax in the event of a Brexit has brought out dozens of his fellow MPs loudly and publicly against him.

The former Tory leader, IDS, says the George is talking “nonsense”. This off the back of Sir John Major declaring some of the most senior Conservative politicians untrustworthy.

So the Rubicon has been crossed.

There is no chance the Conservative Party can go back to business as normal after the referendum.

But more than that, the Tory troubles add to the call for a fundamental realignment in British politics.

The Conservatives may divide left and right – perhaps the disaffected MPs will go to UKIP – but Labour can take no comfort.

Jeremy Corbyn presides over a divided and inward looking party, as stories begin to emerge of Labour members in post-industrial areas voting in droves for Brexit.

As the joke goes, the Lib Dems at Westminster now fit comfortably in an Addy Lee, and the SNP have slipped comfortably into New Labour’s discarded old Pradas.

So if you’re a pro-European Conservative; a Labour voter more concerned with the economy than nuclear weapons; or a Lib Dem who understands globalisation – you’ll be looking for a new home.

People are asking if it’s time for a new movement where modern, outward-looking, individuals with a global perspective and diverse influences can find common political purpose. It’s what the election expert, Professor John Curtice, described to a Cicero Group audience as ‘the second dimension’ – beyond traditional left/right alliances.

Of course the scholars will tell you parties born of protest are doomed to fail – but one thing’s for sure: there’ll be no turning back for this Conservative Party or British politics as a whole whatever the result next Thursday.
