Former deputy prime minister Nick Clegg has said that Michael Gove was the source of the claim that the Queen backed Brexit.
In a March article published in The Sun, the newspaper claimed the Queen had voiced strong anti-EU views during a lunch where Mr Clegg was present.
“Michael Gove obviously communicated it, well I know he did, he gave this to The Sun,” Mr Clegg says in Brexit: The Battle for Britain, which will be aired on BBC Two on Monday.
Mr Gove denied briefing the story at the time, while The Sun claimed it had two sources.
At the time Buckingham Palace complained to the Independent Press Standards Organisation about The Sun's report.
