Rehman attended a networking event in support of the British Transplant Games which are to be held in Medway this year.
Rehman spoke at the event:
"Forty-three per cent of families refuse organ donation because they don't know what their relatives' wishes were. Unless we can make people aware of how they can become a donor they're not going to do it."
Rehman commented: "I fully support the British Transplant Games and the fantastic job they do."
