I’ve barely recovered from the life-questioning shock of hearing the Conservative Shadow Home Secretary (who, disappointingly, doesn’t do shorthand in a really dark house) talk perfect sense about the 42 days fiasco, on the BBC on Sunday.

(He said the measure would foster terrorism rather than defeat it, for a start. He said that mass surveillance and ubiquitous CCTV didn’t prevent crimes. Blimey. We are really through the looking glass now. I would have always thought agreeing with a Conservative would-be minister would be a mark of imminent dementia and here I am applauding his ratioality. Oh bugger.)

Now, it’s the turn of z-list celebs to demonstrate against the 42-day rule.

On principle, I hate celebs assuming that, having shown some skills in the tricky areas of acting, performing music, being born with a famous dad or being prepared to make idiots of themselves in public, their political opinions are somehow especially valid.

But, faced with the BBC’s “Stars urge MPs against 42 days” story, I can only say “Bravo, celebs.”

It seems that only Honor Blackman and Vivienne Westwood made up the celeb contingent that Liberty had assembled, which isn’t much of a celeb crowd, but was at least enough to get the BBC to notice. Plus Chris Huhne (Liberal), David Davis (Conservative Home Affairs representative) and Diane Abbott, a brave and admirable – or “outspoken left-wing ” a/c the BBC – Labour MP. Respect to you all.
