The Tory Party press office was warned last night by Twitter that they face 'decisive corrective action' if they repeat a name-change stunt they pulled during the ITV election debate.

The party re branded its Twitter feed for several hours, changing the name from CCHQPress to FactCheckUK during the debate.

The action was heavily criticised as the re branded account could have fooled potential voters that the messages praising Boris Johnson could have been coming from an independent fact checking organisation, rather than the Conservative Party.

The move was described as 'inappropriate and misleading' by fact-checking organisation Full Fact

Unsurprisingly, the FactCheckUK verdict was Boris Johnson was the 'clear winner'

The microblogging site warned the Conservative Party about their actions which were in breach of the company's terms and conditions.

According to the company: 'Twitter is committed to facilitating healthy debate throughout the UK general election.

'We have global rules in place that prohibit behavior that can mislead people, including those with verified accounts.

'Any further attempts to mislead people by editing verified profile information - in a manner seen during the UK Election Debate - will result in decisive corrective action.'

The Tory Party stunt was widely criticised, including by fact-checking organisation Full Fact.

In a tweet, the organisation said: 'It is inappropriate and misleading for the Conservative press office to rename their twitter account 'factcheckUK' during this debate.

'Please do not mistake it for an independent fact checking service such as @FullFact, @FactCheck or @FactCheckNI.'

The @CCHQpress account is verified by Twitter, displaying a blue tick which is intended to denote that a user is genuine.

Unsurprisingly, the FactCheckUK account found that Boris Johnson 'won' the debate with Mr Corbyn.

The Liberal Democrat press office posted an image suggesting they were reporting the account to Twitter for 'pretending to be me or someone else'.

They tweeted: 'And people wonder why trust in politics has been eroded @CCHQPress'.

Labour's David Lammy tweeted: 'The Conservative Party press office @CCHQPress rebranding themselves as 'FactCheckUK' shows what disdain this party and this government has for the truth.

'The Electoral Commission must investigate and punish this blatant attempt to decieve the public.'

Conservative Party chairman James Cleverly appeared on BBC Newsnight last night to defend the scam.

He said: 'The Twitter handle of the CCHQ press office remained CCHQ Press, so it's clear the nature of the site. The reason we did that was to call out the inaccuracies of the lies that were coming out during the debate - the NHS is not for sale. It has never been for sale, it will not be for sale.'

Mr Cleverly said it was the party's digital team who decided to change the name of their Twitter feed during the debate.

He said: 'The digital team have a remit. I set the remit. They work within that remit. I am absolutely comfortable with them calling out when the Labour party put out complete fabrication in the public domain and we will call that out whenever they do it.'
