Alan Duncan is filmed impersonating his boss Boris Johnson
Watch: Footage suggests that Rory Bremner had better watch out.
Foreign Office minister Alan Duncan might have just got on the wrong side of his new boss in quite spectacular style.
It has emerged that the Tory MP recently said Boris Johnson only backed the Leave campaign so he could succeed David Cameron as Conservative leader.
And for good measure, the FCO minister has done a less-than-flattering impression of the man who went on to become foreign secretary.
The comments and the impression feature in the new BBC documentary ‘Brexit: a very British coup?’
Speaking on the eve of the referendum, Sir Alan tells the BBC’s reporter: “I've always thought that Boris's wish was to lose by one so that he could be the heir apparent without having to have all the... you know, s-h-i-t of clearing up all the mess. That's always been my view of Boris.”
A clip released in advance by the BBC also shows the Tory MP doing his impersonation of the former mayor of London.
Elsewhere in the documentary Tory grandee Sir Nicholas Soames describes Tory leadership contests as “loathsome”, “ghastly” and “hideous”.
And he describes his fellow MPs as "the least sophisticated electorate in Britain".
