Bradford blood donors who are O Rh negative (O-) are being asked to come forward to give blood following the festive period.

There has been a high demand for O- blood, meaning stocks have fallen.

Jon Latham, assistant director of marketing for NHS Blood and Transplant, said: “We would like to urge all O- donors to walk into their most convenient donor session to give blood to help rebuild stock levels.

“We are always grateful to donors who respond to calls such as this and appreciate that in doing so they do give up some of their precious time. Waiting times may vary in the next few days as we try to accommodate all donors.”
