So which pub did Dave leave his integrity in?

This has been Mr Slippery’s worst week yet, and I think we should all be very pleased about that, as it weakens his hold. His whole period in office has been a dangerous fraud, and is now becoming a grave threat to British liberty.

Mr Cameron’s already reaching for the favourite tools of New Labour – surveillance and increased police powers over all of us, while horrible criminals roam the streets wearing pointless tags.

And I am increasingly convinced that the Leveson Inquiry into the press, which he launched, will come down in favour of regulation which will menace press freedom. That freedom is one of the few protections we have against our incompetent, spendthrift and oppressive State.

Let’s begin with the revelation that Mr Cameron drove away from a pub without realising that he had left his daughter behind. I’m not sure this is all that common, actually.

I suspect it is easier to do if you are one of those problem families burdened with two cars, a grace-and-favour country house, a live-in nanny and a personal protection officer.

It’s interesting that he got into more trouble for this than he did for leaving his integrity behind, when he broke his cast-iron pledge of a referendum on the Lisbon Treaty.

I don't know which pub he left his integrity in. Perhaps the landlord still has it and could give me a call, though as it wasn’t very big in the first place it was probably swept up and thrown away with the crisp packets.

But that’s the modern media for you, largely governed by people who have the political understanding of a marmoset – and yes, I am thinking particularly about Mrs Rebekah Brooks who, in her years of authority at The Sun, managed to be a cheerleader for Anthony Blair, Gordon Brown and Mr Slippery, without missing a breath.

What was the price for this? I’m not sure. But the Tory leader’s first article for The Sun – after its miraculous change of mind – contained a strange pledge to fight the war in Afghanistan more vigorously.

So each time I watch military coffins come back from that futile war, the horrible thought crosses my mind that those soldiers would not have died if it hadn’t been for Mr Slippery’s desire for office at all costs.

Disgust is not a strong enough word, really.
