The number of people registered as organ donors in the UK has surged by more than four million in the last five years.

The latest estimates show there are just under 22 million people on the NHS Organ Donor Register as of October 18 this year.

In March 2011 there were an estimated 17.8 million people registered - a jump of 4.1 million.

London has more people registered than any other region in the UK with close to 2.3 million on the list compared to 1.8 million in 2011.

The capital is closely followed by the North West where more than 2.2 million people are registered as organ donors - also up from 1.8 million in 2011.

In Scotland the number of registered organ donors has jumped from just under 1.9 million in 2011 to just over 2.2 million in 2015.

The latest statistics were published by the Department of Health following questions from Greg Mulholland, the Liberal Democrat MP for Leeds North West.
