Mayor of London Ken Livingstone - pictured left - has been fully exonerated for his suggestion that property developers the Reuben brothers – born in India or Iraqi-Jewish parents – should "go back to Iran and try their luck with the ayatollahs".

Peter Keith-Lucas, inquiry officer at local government watchdog the Standards Board for England, found thus:

"Livingstone's remarks cannot have been anti-semitic, in the sense of being directed towards the Reuben brothers on account of their being Jewish, as Livingstone did not at the time believe them to be Jewish."

Now, I’ve got no particular brief for a couple of asset-stripping billionaires. But allow me to make one observation. Livingstone had no idea that two guys called David and Simon Reuben were Jewish?
