I HAVE just had a rather extraordinary evening, the details of which I will spare you but the generality of which I shall share.

I was joined for dinner at the Commons by Steven Moffat and his wife Sue. Steven, you will remember, is Russell T. Davies’s replacement as executive producer of Doctor Who. Sue is a successful producer in her own right and is working on a couple of projects far too interesting and intriguing to reveal here. I’ll simply say that a visit to the government whips’ office and a chat there with the pairing whip, Tony Cunningham, provided some valuable colour for her latest project. Nuff said.

After dinner, Steve kindly agreed to be interviewed by me for my latest podcast, which I shall post here later on Wednesday. This was the first interview he’s done as executive producer on Doctor Who for many months, and I’m very grateful he agreed to do it.

Afterwards, while enjoying a relaxing glass of wine on the Terrace, we were joined by a galaxy of stars who ha been to a Number 10 reception. They included the legendary songwriter Mike Batt (he of Wombles and Bright Eyes fame, among many, many others), James Bond music composer David Arnold, and Fergal Sharkey out of The Undertones.

It turns out Steven and Sue are friendly with David Arnold because he’s written the music for Sue’s latest venture, Sherlock (an episode of which Steven has penned). It was after midnight by the time I had completed my impromptu and not very official tour of the palace for the benefit of my celeb guests. We hailed carriages outside the gates of the Commons.

Steven is one of my oldest friends; given the demands on his time, I was delighted he made time to come over to the Palace for dinner. He is one of the funniest and cleverest people I know. But as a Bond fan, it was an added privilege to spend some time with David Arnold, who is a lovely, very approachable and friendly bloke. And it was great to meet Mike Batt, even though, according to one of my guests, he’s a Tory. But it doesn’t make him a bad person.

I don’t want to give the impression that MPs mix with celebs all the time; I certainly don’t. But it was reassuring and humbling to realise that talented and successful individuals still consider it a privilege to spend time in the Mother of Parliaments, even when her reputation is as low as it has ever been.
