The Times doesn't seem to have printed a word about it; neither does The Independent; the Daily Telegraph has managed a couple of short news pieces (without a specific reporter's name on - I suspect they don't have a Canadian correspondent, and just put it together from wire reports); The Guardian has had 1 report, and 1 commentary piece. The BBC has had pieces online, but I haven't noticed it mentioned on radio or TV (I might have missed brief mentions, I suppose).
Britain manages to almost completely ignore Canadian politics. In addition to the sparse coverage, none of the top 3 (in traffic) political blogs has mentioned Canada at all (Guido Fawkes, Iain Dale, or Liberal Conspiracy - and while the 1st 2 are RWers who have their heads stuck up their arse, the 3rd is properly internationalist - always covers the US in detail) - either for the elections a couple of months ago, or for the current struggle. When the Queen's oldest grandchild married a Canadian,
it wasn't widely covered here. Probably the last time Canada got significant coverage here was the Quebec independence vote. When you consider the BBC had wall-to-wall coverage of the US elections, with, I'd guess, hundreds of employees over there, and the papers were all mad for it too, it's rather poor.
I suspect if you asked our MPs to name the Canadian PM and opposition leader(s), they'd overwhelmingly fail. But the politicians here, or we citizens, don't have any say on the monarch's relationship with the Commonwealth countries - if a country wants to keep her as head of state, or ditch her, that's up to them. As far as what the Governor-General decides to do, I have no idea whether the Queen will be involved, or if she'll leave it entirely up to Jean - since the Queen's been at this for 56 years, it'd be worth Jean asking her for advice, I'd think. She can point to episodes of minority government in the UK, and to what happened in Australia when the G-G decided the PM had to go, back in the 70s.
