Women who stripped for a calendar have struck again and removed their clothes for yet another - their third.

The new publication, secretly shot near Skipton, contains new nude images of the six WI members, whose campaign inspired a block-busting movie - and has made more than £1 million for charity.

The 2007 calendar is again in aid of Leukaemia Research and funds will go into the pot already raised by the two previous publications.

It includes the six women from the Skipton area - Angela Baker, 60, Tricia Stewart, 57, Lynda Logan, 62, Ros Fawcett, 56, Christine Clancy, 53 and Beryl Bamforth, 72 - who forged ahead with the fundraising campaign after they split from the original members of Rylstone and District WI.

The calendar will contain six photographs from the original 2000 publication and six new pictures.

The new images are group shots of all six women, each finished in sepia, like the originals.

But they no longer have the WI craft theme of the 2000 calendar - now a collectors' item.

Instead, photographer Terry Logan, who has shot the images for all three calendars, has made them "light- hearted and humorous".

One photograph shows the women wearing just Father Christmas hats.

His wife Lynda, who has featured in all three calendars, said: "It was Leukaemia Research who approached us to do this one. We hadn't intended doing another.

"But they said there was still demand for the original and they believed another would be a success.

"When we saw the proofs of the new ones, we were absolutely thrilled to bits. They have a lovely atmosphere."

She said the calendar girls' fund, which contained cash from the second calendar released following the movie, was now ploughing on into its second million and stood at about £1.2 million.

"We are still in demand for all sorts of things, after-dinner speaking and different launches and people are still very generous," she added.

Mr Logan said: "We decided not to follow the original craft theme and have made them light-hearted and humorous.

"I don't want to give anything away just yet, but one has the girls just wearing Christmas hats."

The new calendar will be launched at a special event at the Home Show at the Excel centre in London's Dockland on Thursday, April 20.

A Leukaemia Research spokesman said the new photographs would not be revealed until the event.

"The decision to go ahead was made because of the demand. Everywhere the calendar girls go they are urged to do another one," he said.

The six women adopted the title The Baker's Half Dozen after the original 11 split over the making of the film version. The six worked with London-based Harbour Films, which won backing from Hollywood.

The original calendar was launched in memory of Mrs Baker's husband John Baker, the Yorkshire Dales National Park officer who died of non-Hodgkins Lymphoma in 1998, aged 54.
