On the eve of World Kidney Day, Adrian Mole Author Sue Townsend - who underwent a kidney transplant operation last year - is appealing for people to come forward as altruistic donors.
This is when a healthy person offers a kidney anonymously. Last year 15 such donors were approved.
The Leicester author makes the appeal ahead of World Kidney Day on Thursday, where the campaign is focusing on diabetes affecting people like her.
She will be a guest on Wednesday's Daily Politics on BBC2, the programme starts at 1130 and she is due on around 1240.
