The Prime Minister and the leader of the opposition have provided recipes for a new charity cookbook.Gordon Brown and David Cameron are among the dozens of famous names to have contributed to the Saints and Celebs Cookbook, which was dreamed up by two parishioners at All Saints Church in Ilkley, West Yorkshire.The favoured recipe for the current incumbent of number 10 is vegetable and mozzarella parcels, while his opponent in many a parliamentary debate favours sausage meat pasta.Sybil Mussell and Dorothy Tinkler wrote to a number of important public figures and celebrities to ask for recipes, each accompanied with an anecdote, for their ingenious book the proceeds of which will be used to raise funds for their local church.With environmental policy high on the agenda for both these influential figures, they might well be the proud owners of a food waste disposer unit, such as a model from Frankes well-designed and reliable range of products.
