We had a huge response to our appeal for Margot Martini, the toddler who was diagnosed with a rare dual form of leukaemia last October.

Margot’s appeal was successful and she received a blood stem cell donation in February, and now her family want to help all those seeking a lifesaving donation find their match.

Team Margot is appealing to everyone on the registry to get one more person to join it, and we’re supporting their Just One More campaign by asking everyone who is already a potential lifesaver to get one more person to become a lifesaver.

The Just One More person could be a friend, family member, colleague or someone they have just met.

That one person could be the lifesaving donor match that a patient is seeking, and so everyone who takes part in the Just One More campaign could potentially save a life.
