Neil O'Brien, MP for Harborough, was joined in his support for the Match4Meena campaign, by Home Secretary Sajid Javid MP.
The campaign seeks to recruit new registrations to the stem cell donor, to help fight blood cancer.
Meena Kumar from Oadby was diagnosed last year and is currently searching for a match.
Neil said, “This is a hugely important campaign and I’d encourage anyone reading this to join the register as a stem cell donor.
It was great to have the Home Secretary supporting Meena’s campaign and this message also; it isn’t an exaggeration to say it could save a life, and we need as many people to join as possible.”
