The intervention of Mr Corbyn was hardly such an event. It had been delayed by the efforts of his staff to erase from his (and Labour's) websites the record of his recent past anti-EU comments in order to clear the way for his announcement of brotherly support and comradeship for Mr Cameron's Remain campaign.

The speech did not go well. Of course it was derided by the usual suspects, but of course it was endorsed by the Guardian. To their credit however, the guardianistas at the BBC simply could not bring themselves to lavish him with praise. Indeed, they rubbished his statistics.

Mr Corbyn had spoken movingly of the possible fate of the 750,000 British nationals living in Spain and the more than 2 million more living elsewhere in the EU in the event of Brexit. However the BBC "Reality Check" concluded that the real figures for British permanent residents were more like 306,000 in Spain and 1.2 million in all the continental EU states including Spain. Even for Mr Corbyn, that is either deception or delusion on a grand scale.

No wonder that the tax returns which he has made public seem to have omitted substantial items of his income.

To be fair to Mr Corbyn he is far from alone in having the BBC pick holes in his claims about the likely effects of staying in, or of leaving the EU., although it is some comfort that the Corporation confirms that we pay our Masters in Brussels a good £8 billion more than it gives back here in return.
