Mr Williams accepted the award in recognition of his crucial help with the successful campaign to secure comprehensive smokefree legislation.
The current plan, which is central to further improvements to cancer services, is due to run out in 2010. The charity had been arguing that it is vital the Government starts planning now to take account of future challenges, including rising cancer incidence, improved survival rates, advances in treatment and the evolving structure of the NHS itself.
"Now with his help and the petition signatures of over a quarter a million people, we've also succeeded in persuading Ministers to start planning now for future cancer challenges. We're looking forward to working with them to ensure the proposed Cancer Reform Strategy addresses recent changes in cancer incidence, survival rates, treatment and the way the NHS works".
