They started their day at County Hall, where they spoke at a reception with the charities that are a part of the Heads Together campaign, and talked to people who have received help from someone in their family or social circle during in crucial moments in their lives, along with the person who provided that support.

Later on Monday, the London Eye will be lit up in purple in support of World Mental Health Day, joining other buildings around the world that will be doing the same and connecting Heads Together with the worldwide movement to end stigma around mental health.

We'll be seeing more of the Duke and Duchess later this week. This Friday, the royal couple will carry out another joint engagement in Manchester, England, where they will visit a hospice opened by William and Harry's late mom Princess Diana in 1991.
