He was a bit silly to talk so unguardedly to a man who had dug his garden up (?) but I find it absolutely that anyone has suggested that this should be a resignation issue. It's pretty obvious he was just expressing what everyone is thinking, and there are real problems with MP's remuneration and exes.
It seems that, every time anyone says anything remotely off-message, you get shouts of "resign!" Very glad to hear that he's not going to go but how ridiculous to haul someone over coals for something so minor. Honestly, who cares? Can MPs not express opinions, even in private?
When did this become the norm? (see also the BBC's mania for falling on its sword)
