Cameron has always been slimy in the way he goes about business,do not expect him to stand down and resign over this and most likely will just rally the troops behind him like usual.
He seems to be at his happiest at weapons´sales conventions. I think he´s a bloody warmonger. Cozies up to the Saudis and grovels before them and other scumbags of that ilk.
The biggest problem is, it's not just him, though. The whole crooked lot need locking up. I suspect the tories would have demanded he step down already, if it weren't for the fact that they can't find someone who isn't morally bankrupt in the party to replace him with.
