BBC subtitles make it look like Jeremy Corbyn is congratulating ‘Harry and Hezbollah’ on royal engagement

BBC producers made an embarrassing gaffe today - as they wrongly said Jeremy Corbyn was congratulating Hezbollah terrorists.

A subtitles fail made it look like the Labour boss was praising Hezbollah during his response to Prince Harry's engagement.

After giving a speech in Scotland, reporters asked Mr Corbyn - a committed republican - for his reaction to news of the new royal wedding.

He replied: "I wish them well, I hope they have a great time and great fun together, and having met Harry a couple of times I'm sure they're going to have great deal of fun."

The Labour leader then added: "I really do admire the way that Harry and his brother have drawn attention to mental health conditions all across the country."

But when his speech was broadcast on BBC News, a fault with the subtitles introduced an unfortunate error.

The text read: "I really do add my the way Harry and Hezbollah have drawn attention to mental health conditions."

The BBC subtitles are believed to be operated by automatic systems which are then corrected by human supervisors.

A BBC spokesman said: "The voice recognition technology used when subtitling live news broadcasts misrecognised the phrase ‘his brother’ leading to the error, which was corrected onscreen."

Web users took to Twitter to mock the hilarious blunder today.

Mr Corbyn has previously sparked huge controversy by speaking alongside members of Hezbollah.
