Chocolate-lovers were given a cheeky invite to unwrap an original Calendar girl for charity.

Three of the Women's Institute members who stripped off for a charity calendar helped unveil a box of chocolates bearing their image. They hope sales of the sweets will help top up their fundraising to the £2 million mark. Skipton chocolatier William Whitaker has used the nude images of the girls of the Rylstone Women's Institute to create a cheeky chocolate box, with proceeds going to the charity Leukaemia Research.

Angela Knowles, whose husband John Baker died from non-Hodgkin's Lymph-oma and inspired the calendar, was joined by fellow pin-ups Beryl Bamforth and Tricia Stewart at the launch at Waitrose in the Brunswick Centre, London.

Mr Whitaker, who owns Whitakers Chocolates in Skipton, has wrapped 12 pieces of plain chocolate in images from the original calendar which was a resounding success when it was first put together in 1999. The boxes are on sale for £1.99, with 20p going to charity.

The 1999 calendar became a sensation, outselling those of Britney Spears and Cindy Crawford.

In 2003, their story was turned into a Hollywood film starring Helen Mirren and Julie Walters which proved to be a major hit.
