He has been volunteering at Shout 85258, which offers support via text message to people in personal crisis.

Those texting the round-the-clock service would not know they are talking to a member of the Royal Family - like Shout's 2,000 volunteers, William would use a pseudonym on the platform.

The Cambridges and the Duke and Duchess of Sussex helped to launch Shout 85258 last year - investing £3m in the service via their Royal Foundation.

Training as a crisis volunteer at Shout puts William in the frontline of services for young people in distress - and it's a tough role.

The fact that the second in line to the throne is now routinely helping people in such desperate situations is hugely significant - it gives Prince William a unique perspective on what young people in crisis may be going through

Meanwhile, the Duchess of Cambridge has been calling people who are self-isolating or vulnerable, as part of the Royal Voluntary Service's NHS Volunteer Responders scheme

The royal couple marked Volunteers Week by holding video calls with those helping charities in England and Wales
