The Conservative Party has been sharply criticised by a UK fact-checking agency after it rebranded one of its Twitter accounts.

The @CCHQPress account - the Tory press office - was rebranded as "factcheckUK" for Tuesday's live TV debate involving Boris Johnson and Jeremy Corbyn.

Conservative Party chairman James Cleverly defended the rebranding.

He told BBC Newsnight: "The Twitter handle of the CCHQ press office remained CCHQPress, so it's clear the nature of the site."
