Arrested Canadians wanted to behead Prime Minister [AV]

Canadian Press reports that:

One of the men charged with plotting to stage a massive terrorist attack on Canadian soil also allegedly expressed a desire to behead Prime Minister Stephen Harper.

Prime Minister Harper has been one of the most forceful defenders of Canada's continued involvement in the war on terrorism, and since being elected several months ago has been very popular in the polls.

The Canadian Press article notes that the attack on the Prime Minister was supposed to occur while he was in the House of Commons. Although there have been no serious breaches of security in the Canadian House of Commons in recent years, evidence from the UK suggests that Westminster-style parliaments are not impregnable.
