How the Queen teased 'Europe bore' Cameron over his stage alter ego in their real weekly Audience David Cameron 'laughed like a drain' at stage portrayal The Audience Hit play dramatises the weekly audiences Queen has with Cameron It is a witty scene that has had West End audiences chuckling in the stalls: the Queen dozing off as David Cameron bores her with the latest political machinations from Europe. But now it has emerged that the real Monarch got wind of the portrayal - and used it to tease the Prime Minister himself. In one of their regular meetings, Her Majesty told Mr Cameron she was aware of the fictional scene, and assured him that in real life she had never fallen asleep during their Buckingham Palace briefings. Private: A real audience between the Queen and David Cameron at Buckingham Palace Then after a dramatic pause, she added: "Yet!" Is it the sort of perfectly timed waspish wit that the stage version of the Queen, as played by Dame Helen Mirren, would display - making it a bizarre example of life imitating art, imitating life. And after Her Majesty told Mr Cameron about the scene in The Audience, he made a point of going to see the play - and he "laughed like a drain" at the pivotal moment. The acclaimed show depicts the private audiences the Queen has had with the various Prime Ministers of her 60-year reign - but the exchanges came entirely from the imagination of playwright Peter Morgan, as the meetings are shrouded in secrecy, with no written records taken. Yet Mr Cameron let slip this small detail of his audience with the Queen when he met one of the show's producers, Andy Harries, at a party while on holiday in Ibiza last month. Hit West End show: Rufus Wright on stage as David Cameron, right, and Dame Helen Mirren as the Queen The Prime Minister may come under fire from traditionalists for blurting out her candid comments at a social function, but given the innocent and light-hearted nature of the exchange - and the Queen's evident sense of humour - it is unlikely to cause a constitutional row. Mr Harries told The Mail on Sunday: "I was sitting next to Mr Cameron at a party in Ibiza a few weeks ago and we were having a glass of wine. He remembered that I had produced the film The Queen [in which Dame Helen also starred] - and I told him I was involved in The Audience, and that he was in it. He said he hadn't seen it, but was very keen to do so. He said the Queen had asked him about the play in one of his real audiences with her. She said, "I understand there is a play about our meetings and it shows you going on about Europe after you have been to a summit in Brussels and me falling asleep - when I haven't done, have I? Yet. She left a pause before the "yet." Mr Cameron told it in a most amusing way. It's known the Queen has a sense of humour, but she clearly has good timing too. Mr Cameron came to the play shortly afterwards and laughed like a drain. Night out: David Cameron with his wife Samantha holding a programme after seeing Helen Mirren in The Audience Buckingham Palace and Downing Street declined to comment last night, on the grounds that the privacy of the meetings is a key plank of the relationship between the head of the government and the head of state. But well-placed sources did not challenge Mr Harries's account. By tradition, the Prime Minister informs the Queen of his Government's latest plans and any secret diplomatic issues during their audiences. For her part, the Queen can act as a sounding board and offer her advice to the PM. According to Royal protocol, both parties are strictly forbidden to repeat a word of the confidential discussions - even to their spouses. The Audience - and Dame Helen's portrayal of the Queen - won rave reviews from critics and attracted sold-out houses. It finished its run at the Gielgud Theatre earlier this month, but Mirren is set to star in a version on Broadway next year. The actress hit the headlines during the London run for delivering an expletive-ridden rant at a drum troupe while she was still in costume as the Monarch, as their playing outside the theatre disturbed her performance. The production recreates the Queen's audiences with her 12 Prime Ministers, who her character calls "the dirty dozen," including John Major, Gordon Brown, Harold Wilson, Sir Anthony Eden, Margaret Thatcher and Sir Winston Churchill. Scenes were often rewritten to reflect current events, and she was shown to fall asleep while Mr Cameron talks her through the latest developments on the euro crisis.
