Jewish News staff members joined the campaign to help Londoner Sharon Berger, 65, who was diagnosed with acute myeloid leukaemia in 2012.

The only available cure is a stem cell transplant from an unrelated donor and, despite having a transplant in 2013, the cancer has returned. Sharon has been told she has less than a month before she needs a second transplant.

A spokeswoman for DKMS said: “It is wonderful that the team at Jewish News are taking the time to swab to become potential blood stem cell donors. It could lead to them saving a life, which could be Sharon’s or another person in need of a lifesaving donation.”
