Among the many items swamped by yesterday's eruption of royal marriage lava was an instructive display by London's mayor Ken Livingstone at a party to celebrate the 20th anniversary of the Labour MP Chris Smith coming out as gay. According to the Times, it seems Livingstone lashed out verbally at an Evening Standard reporter whom he accused of working on a paper with a history of fascist sympathies (a reference to the war-time record of the Standard's stablemate, my own paper the Daily Mail) and on being told he was a Jew said he was was behaving 'just like a concentration camp guard'.

This is hilarious. When it comes to supporting fascism and Jew-baiting, this is the same Ken Livingstone, let us not forget, who embraced Sheikh Yusuf al Qaradawi, the prominent jurist who has expressed venomous and even lethal prejudice against Jews and gays.

It was always possible that Livingstone really didn't believe that Qaradawi had said such things in the past. But now he himself has accused a Jew of being like a Nazi.

If it looks like a duck, walks like a duck and quacks like a duck...
