The Business Secretary Vince Cable today confirmed his intention to star in a Christmas edition of Strictly Come Dancing.

If, as seems likely, Vince Cable accepts the BBC's invitation to appear on a Christmas special of Strictly Come Dancing, he will no doubt wow the public – he has been a keen ballroom dancer for years. The best thing about this story so far, however, was the total bemusement yesterday of the two presenters on the American business channel CNBC who dedicated a good five minutes to discussing Mr Cable's appearance. Though the US has its own version of Strictly – Dancing With The Stars – the US Commerce Secretary, Gary Locke, is not thought to be planning an appearance.

BBC1 and BBC2 are too similar, while BBC4 needs to do more to raise its profile, the BBC Trust said yesterday after a review of the output of the channels.

"Ann Widdecombe is up for a laugh and seems to be enjoying herself. She is being very entertaining – light entertainment harms no one."

As Gavin Henson considers swapping the sequins of Strictly Come Dancing for the red star and crescent moon of the Saracens rugby club, and a possible return to the international fields he was born to inhabit, we can only deplore again some of nature's more slipshod habits.

Saracens have confirmed they have made contact with Gavin Henson as a possible solution to their potential problem at fly-half.

Miss Selfridge launched its mid-season sale this week, with up to50 per cent off selected items until Tuesday 19 October. Visit http://ind.pn/dqiDiE for the full list of savings, with the "hot picks" section (a glorified list of the biggest discounts) well worth a look. When making your order, don't forget that Miss Selfridge offers free delivery on all orders over £80. You don't need a voucher code to take advantage but I thought I'd mention it as delivery charges may alter the way you shop.

Visual Arts: I saw a really great show of Wolfgang Tillmans at the Serpentine Gallery. I saw Wolfgang's first show at Maureen Paley back in 1993. It really wasn't like anything I had seen before; casual images pinned to the wall, with tenuous links between them. Wolfgang has continued being experimental without losing that lightness of touch, and always keeping that sense of humanity.

The chances of Gavin Henson representing the Barbarians in December hinge on whether he is more like former England scrum-half Matt Dawson or fellow Welshman Joe Calzaghe on the Saturday night dancefloor.
