William attended an event held by the NSPCC in Parliament today (10.10.2016) where he found out more information on the work that the NSPCC are doing to stand up for children.
The NSPCC launched a campaign called '#Itstime' on world mental health day to ensure that children and young people are not left behind in the drive to improve the understanding and treatment of mental health illnesses.
