There is a complete absence in the Labour leadership contest of what we like to call the ‘big beasts’. They are all minnows.

How can we explain the ‘Collective’ madness that has taken over the Labour Party? I have just returned from lands of former Collectives (mega farms set up by the Communists) in Latvia and Lithuania, and I can tell you that Jeremy Corbyn’s much admired legacy to those once Communist countries is a nightmarish one.

The man might come across as a sincere idealist – not at all like the serried ranks of the career politicians so many disdain today – but the likes of Jeremy are the ones to fear the most. They are the zealots, cast in the mould of that ‘sea-green incorruptible’, Maximilien Robespierre, of the French Revolution. While on the subject of the quiet, softly spoken, hard-to-rile idealist, was not ‘Uncle Joe’ Stalin exactly that sort of man? He, however had a term for the likes of sweet natured, but for us dangerous, men like Jeremy Corbyn; useful idiots.

And while an old geezer, myself, isn’t it a bit odd that so many young people appear so much in love with old geezer Corbyn? It’s all a little perplexing. If I were to make a guess as to part of the reason – and in life there are, more often than not, many reasons – I would say it is illustrative of the depth of public disenchantment with the political class. And when a man comes forward, however misguided, who is clearly a man of conviction and seems authentic, the young grab at him.

Another factor, surely, is the complete absence in the Labour leadership contest of what we like to call the ‘big beasts’. They’re all minnows. Alan Johnson might have qualified for that sobriquet, but he doesn’t want to know. Perhaps he’s canny enough not to risk losing his sanity in trying to bring together such a disparate band of brothers in what he might view as a poisoned chalice.

Then there’s that totally toxic Blair legacy. We won’t speak of the horrors of the Iraq war or the dodgy dossier that deceived us into sanctioning an illegal war, but there is such a litany of other failed measures that found their way on to the statute book that I might cause you to develop apoplexy half way through were I to attempt to list them all.

His favourite ‘Blair Babe’, Tessa Jowell, loves pontificating and acting as cheer leader for the Bambi project, but she would be better advised finding some stone to crawl under. It was she, who as Culture Secretary, allowed round-the-clock drinking, which has turned all of our city centres into no go areas for the majority of people at weekends. Worst of all the things she did was to promote online casino gambling – that egregious, family-wrecking Act which flies in the face of everything the titans of Old Labour stood for. These titans were high-minded men of probity, who among their other fine and compassionate qualities was a determination to uphold individual dignity and family life. Gambling was anathema to them.

Despite Corbyn’s phenomenal rise against the odds, one or other of his pigmy opponents may yet come through in the race to succeed disastrous Ed Miliband. But even if that were to happen, what does the whole business tell us about the present state of the Labour Party? Could a split prove terminal?

We have grown so used to a duopoly of political power that we could be forgiven for thinking that Tories and Labour are a permanent part of the political landscape. But even in the 20th century this was not the case. The party of Lloyd George seemed just as permanent on the eve of World War One. For much of the previous century, that Liberal giant of principled government, William Gladstone, bestrode the political firmament. Then, after Lloyd George, the party became an irrelevance. Following their brief re-appearance and engagement with power under the recent Coalition, they have again sunk back into irrelevance. Is it now, as a result, a return to business as usual? Not necessarily.

Whether Corbyn succeeds or not, what his extraordinary success has shown is the deep schism within the Labour Party. It may prove unbridgeable. Certainly it will take more than any of the lightweights on offer to heal the wounds of what is turning out to be a bitter, acrimonious fight. Tories may gloat over what is going on, but they would be wrong to do so. Any properly functioning democracy needs an effective Opposition. You cannot expect the media to perform this role alone, splendid though it is in exposing maladministration and wrongdoing. (How incredibly right it was to resist Leveson’s proposals to muzzle it. Do you seriously think the establishment would have allowed itself to be investigated for child abuse had those proposals gone through?)

There is now, as I see it, a chance for a regathering of the forces of the sensible Left to challenge an overweening government. Essentially the Liberal Democrats are a left-of-centre party. Were they to throw their lot in with similarly minded elements in the Labour Party, it could consign forever to the dustbin of history that Trotskyite wing of Labour that so bedevils its chances of regaining the trust of the British people.

It might, in the process, appeal to those many citizens north of the border and in Wales who still have faith in a Union which has shone so brightly for so long and raised us, a small people, so high among the nations of the earth.
