The 32-year-old royal visited the headquarters of London Ambulance Service in Waterloo, south east London on Thursday (02.02.17) where he spoke of the importance of talking through these issues.

He shared: "If people in the green uniform aren't coming forward and talking about it, people driving blue light vehicles in general aren't talking about it, then the rest of us aren't going to talk about it.

"You guys are literally right in the thick of it, and to be able to carry on and operate at a really high percentage and be on your game the whole time, you need to come back and just get rid of all that - it's unnecessary baggage.

"We're all human, we're not machines, despite a lot of people in certain jobs having to think and behave like machines in order to get the best out of you - I accept that - but it's not weakness, it's strength to be able to come forward, deal with it, move on and be a better person."

Prince Harry, his brother Prince William and his sister-in-law Duchess Catherine are long-time supporters of reducing the stigma surrounding mental health.

Prince William said recently: "Mental health matters to each and every one of us. It matters just as much as our physical health. The crews I have worked with, whether RAF Search and Rescue or Air Ambulance, must take their mental health as seriously as they do their physical health or else they would not cope - and, actually, that is true for everybody at some time or another in their life. There are times when, whoever we are, it is hard to cope with challenges - and when that happens being open and honest and asking for help is life-changing."
