Oh dear. Whatever your political beliefs, Prime Ministers should not wear a keffiyeh. I mean, I doubt whether he'd do the same if someone asked him to wear a Barcelona or a Real Madrid scarf. But does wearing it immediately make him anti-Semitic, as interested sections of the press are suggesting? Probably not. An idiot, perhaps, because this surely damages any contribution Spain might have made to possible peace negotiations - but not necessarily an anti-Semitic idiot.
