collapse of the current UK government

Wishful thinking I'm afraid. The Limpdems must surely be the most principled party on earth -- they keep locating important principles that they haven't betrayed yet, and promptly betray them. I expect they'll find a way of backing down on press regulation next week.

And even if they don't -- there's no reason it should be a coalition-breaker. Cameron has already declared that if he loses the vote in the Commons, he will "accept the sovereignty of Parliament". Mighty big of him, when you think about it.
