William, Kate and Harry will urge nation to start conversations about mental health

The Duke and Duchess of Cambridge and Prince Harry will join forces on Tuesday to urge the nation to talk about mental health as they ramp up their work for their Heads Together campaign.

In a rare joint public engagement by the royal trio, they will ask all of us to “start conversations” about mental health to break down the stigma surrounding the subject.

They will also encourage people to come forward with new ideas about how the country’s attitudes to mental health can be brought into line with the way physical health is viewed.

Heads Together was launched by the Duke and Duchess and Prince Harry last year with eight charities with the aim of changing the national conversation on mental wellbeing.

It will be at the centre of the royal trio’s public work as they build towards the London Marathon in April, of which Heads Together is Charity of the Year for 2017.

On Tuesday they will address a gathering of business, charity and media leaders in London to encourage them to back the campaign.

A spokesman for the three said: “They will say that the most important thing we can do is to start a conversation about mental health. That might be seeking help if you need it, or talking to someone you think might need help, or just starting a conversation with friends and family about the subject. “Over the next few months the campaign will also be showing people how they can have that conversation.”
