Boris Johnson has been accused of burying the findings of a parliamentary inquiry into Russia's influence over the Brexit referendum result.

The chair of the UK Parliament's Intelligence and Security Committee on Thursday accused the prime minister, who led the campaign to leave the European Union, of sitting on the report, which was sent to him weeks ago.

Member of Parliament Dominic Grieve said that his committee had sent the report on Russian influence on UK elections and referendums to the prime minister two weeks ago, but Downing Street had failed to sign it off.

He called on Johnson to allow its publication before the UK goes back to the polls in the upcoming general election.

"The Intelligence and Security Committee of Parliament, of which I am the chair, has been investigating the threat posed to this country by Russia," he told the House of Commons on Thursday.

"Parliament ought to have and must have acccess to this report in light of the forthcoming election and it is really unacceptable for the prime minister to sit on it and deny them that information."

Parliament's Intelligence and Security Commitee has access to key players in UK intelligence agencies and often conducts sessions behind closed doors.
