PUPILS at Rhyddings Business and Enterprise School, Oswaldtwistle, received a letter of encouragement from Tory party leader David Cameron after they sent letters to politicians as part of a project about renewable energy sources.

Mr Cameron wrote: "I hope that what you are learning in your science class will inspire many of you to consider a career in science and technology so that you can help to develop the technological solutions which will help us preserve our environment in the future.

"May I wish you the best of luck and continued success learning about these important issues."

Science teacher Gary Merritt said: "We are delighted that David Cameron has found time within his hectic schedule to respond."
