The Duke of Cambridge has spoken about how dealing with male suicides in his work as an air ambulance pilot has affected him and driven him to campaign on the often taboo issue.

The Duke said that his very first call-out after joining East Anglian Air Ambulance was to a male suicide, which made him "realise starkly" how big a problem the issue is.

Suicide is the biggest killer of men under the age of 45 in the UK, and 76 per cent of all suicide victims are men. The Duke was "staggered" to find out the scale of the issue.
