For those involved at the centre this is one of those golden periods rare in politics. It comes maybe once in a long career, when your opponents decide to do exactly what you need them to do, when the electoral stars align perfectly and the waters part. It is for a few weeks as though you are living through the manifestation of a miracle.

Most politics, most of the time, is mundane and for the senior aide or tribal strategist usually nothing turns out quite as you desire. Until this, something almost magical, happens. What Labour in Britain is experiencing right now is the political geek equivalent of childhood dreams coming true, of winning the World Cup or taking the gold medal in the Olympics 100 metres final or winning the lottery.

Less than five years after it was marmalised by the Tories in 2019, Labour stands on the edge of a super majority, with a Socialist leader about to smash the Conservatives and ensure an opposition so shrunken that there will be no meaningful opposition in the House of Commons for the next five years.

How is this happening? Several trends are converging. Sir Keir Starmer’s overhaul of the party has worked, by persuading undecided voters and former Tories to back Labour on a simple “get this lot gone” backlash against the Conservatives. After Johnson, Truss and Sunak, voters have had enough. Plus, incumbent governments everywhere are feeling the wrath of voters following Covid and inflation.

What makes it worse for the Tories is that what is left of the centre-right vote in England is splitting too at precisely the right moment for Labour.

Reform (a party/company controlled by Nigel Farage) is polling somewhere between 8-14 points. If this persists it will let Labour and the Lib Dems through in seats the Tories might otherwise hold. That will further increase Labour’s majority.

And in Scotland, the SNP is also collapsing, opening the way to Scottish Labour becoming the largest party north of the border.

Helpfully, for Labour, the Prime Minister also botched the launch of his early election. There was a good case for going early but not for being unprepared and so haphazard that the abiding image is of a drenched PM looking sad in the rain.

Since then the Tories have focused on almost begging older voters not to abandon them and accusing Labour of having no plan, which amounts as Tim Montgomerie says to saying “ooh, that Keir Starmer, he’s a bit vague.” Instead the Tories would surely be better saying Starmer has a secret plan, rather than no plan, to raise taxes and be maximum woke.

To the horror of the Conservatives, the polls are not narrowing. The one outlier still gave Labour a lead of 12 points last week. Most other polls give Labour a lead of twenty or more points. This suggests Labour is heading for a majority bigger even than 1997 and quite possibly on a par with Baldwin’s majority of 209 in 1924 when the Liberals collapsed or the Whig majority of 224 after the 1832 election.

While the glee of Labour tribalists and also those sick of the Tories is understandable, we should all be very wary of what is about to happen. Not just because governments with overly large majorities have a tendency to trend towards arrogance and hubris over time.

Last week we got a glimpse of the future, in the row over Diane Abbott and the Labour leadership’s attempts to ensure she could not stand in the general election. Abbott holds some ridiculous views but if the leadership was going to remove her it did not need more than a year of lawyerly chiselling. The process was dragged out and her treatment was downright cruel.

The hiding behind process, the hatchet faced bureaucracy, the lack of empathy, the control freakery – it had an almost East German grey quality.

Those of us who have seen before how this movie ends know that we should pay attention to how a party leadership group behaves towards its own side. When they behave this way towards each other it is a glimpse of how they will treat the rest of us in the end.
