Rocker Pete Doherty stunned organisers of an art exhibition when he submitted a picture - drawn in his own blood.

The We Love Marlborough group approached the Babyshambles singer, who lives in a rented house in Savernake Forest, to ask him if he would support an exhibition called Get In The Gallery.

The exhibition, aimed at four to 18-year-olds, appeals for entrants to submit a painting or drawing on a postcard.

Mr Doherty was approached by WLM committee member Peter Davison, who is also chairman of Marlborough Chamber of Commerce to help publicise the exhibition.

"Without hesitation he said he would not only be delighted to support it but would also do a postcard painting for it,'' said Mr Davidson.

Mr Doherty, who is touring in Belgium with his band, said: "It's a really good idea and I'm happy to be able to do something for it.'' But the organisers were taken aback when he submitted his postcard painting showing his Babyshambles Band done in blood.

He had annotated it with musical clefts and a poem in French.

Mr Davison said: "It's clear that his knowledge of French is superb.

"The aim of the exhibition is that it's anonymous and people will only learn who the artist is if they buy a postcard,'' said Mr Davidson.

"It should be pretty to ascertain which one is Pete Doherty's because true to his style he has painted it in blood.

"I can't think we will get many postcards painted in blood, not unless one of the children had a nosebleed while doing theirs."

Other members of Babyshambles have also painted postcards for the exhibition which runs from July 8 to 10 at the Morgan Boyce Gallery in Hughenden Yard, Marlborough.
