Boris Johnson was left spluttering as he launched the Conservative Party's manifesto after being asked a direct question regarding his party's 'fake news' Twitter account.

The party faced major criticism last week after rebranding its press social media account as a fact-checking service named FactCheck UK during a TV leaders debate between the Prime Minister and Jeremy Corbyn.

Earlier today, Mr Johnson was in Telford taking questions following the launch when he was confronted by a journalist from The Guardian over the changes.

The CCHQ Press user was renamed during the debate, with the party's logo switched to match.

Throughout the course of the debate, the account posted claims alongside the word 'Fact'.

The party was told they had misled the public in an official statement by Twitter, who said it would take 'decisive corrective action' if anything similar happened again.

After his manifesto speech, a Guardian journalist asked the Prime Minister if the temporary rebrand had undermined trust.

But after an initial few seconds to collect his thoughts, he responded: “Well, I’m afraid that the Twittersphere is not really my province.

“But what I can say is that, um, I’m informed that, that Labour has some sort of operation, which is, er, very similar to this but I haven’t followed this Twitter stuff with perhaps the attention that you would like."

He failed to directly answer the question, and instead turned his attention to the Labour party, who he said was the real source of damage done to trust in politics by deciding to remain neutral in a second Brexit referendum.
