Michael Crick's piece about the strange disappearance from circulation of the photograph of David Cameron as a member of the Bullingdon Club and the discovery of the uncropped picture of Tony Blair's rude student gesticulation provoked a big reaction from viewers.
Many thought we were wrong to delve into their youthful indiscretions, but that was not really what the item was about. It was about the suppression of photographs which could have proved embarrassing for our political leaders.
The issue is airbrushing from history - a big feature in Orwell and Stalin - and surely one for Newsnight.
Interestingly, it's not at all clear who has done the suppressing in these cases. The photographic company who own the copyright on the Cameron picture are adamant they weren't leant on, but made the decision for commercial reasons. The Conservative party say they didn't ask for it to be withdrawn, though they admit they thought about it when they feared Labour would use it in an election poster.
The unexpurgated picture of Tony Blair has been around for years, but apparently no-one has ever published it. Indeed one version I've seen has the offending gesture blacked out. How odd.
