Portsmouth's Spinnaker Tower is be turned purple tonight to mark World Kidney Day. The NHS Trust said the area is the most generous in the country with eleven people donating their kidneys to strangers last year - eighteen percent of the total of altruistic kidney donations in 2012.

There are 7000 people on the transplant list and 300 people die a year waiting for a kidney transplant.

Since July 2007 when the first altruistic donation took place, a total of 158 altruistic kidney donations have taken place in the UK, with 21 of these taking place in Portsmouth.
