Self-styled style experts Trinny and Susannah may not survive poor ratings for their ITV1 show Undress the Nation, according to one report.

Trinny and Susannah moved to ITV from BBC in 2005 in a £1.2 million deal, ditching their popular What Not to Wear series in the process.

But Undress the Nation has only been watched by 2.5 million viewers recently, less than 12 per cent of the available TV audience, according to The Daily Mail, which suggests the posh pair are facing the axe.

It reports an ITV insider saying: “The show has been a huge disappointment. They paid a lot to bring them over, but they won’t be renewing the current deal.”

Officially, ITV bosses say no decision has been made about their future, although the Undress the Nation will return for a further series in the autumn.
