The princess will shadow a family during a normal visit, starting with the security procedures that must be followed before visitors are allowed to enter the institution, a Category C men's prison and young offender institution housing around 1,100 prisoners.

She will hear about the impact this has on families and will learn about the recent efforts HMP High Down has put into practice to make the experience more positive for children in particular.

Later serving prisoners working with The Forward Trust will discuss with Kate their experiences and the support they are receiving from the charity and prison.
