Adrian Sudbury is a young man who has been diagnosed with 2 types of leukaemia. His bone marrow transplant has failed but it hasn't stopped him trying to get more people to sign up for bone marrow donation. He has a Downing Street petition running at the moment. Please click HERE to read his blog. Regular readers of my blog will know that this is a subject very close to my heart after losing my son to leukaemia 18 years ago.
