Two and a half year old Francesca Dale, of Caterham, Surrey, is seen with a cake of the Big Ben clock tower in London today (27/09/12);  Francesca supported by the Rainbow Trust, is currently undergoing treatment for a cancerous tumour on her face. The cake, thought to be the largest of London's landmark clock tower, was made for the annual 'Big Hour Cake Sale' taking place in Canary Wharf from the 22nd to the 28th of October in aid of the Rainbow Trust, a charity that helps support families of children with life threatening or terminal illness.
