Kate Middleton will launch her first solo campaign helping disadvantaged kids avoid addiction and mental health issues.

Alex Matthews, a journalist for The Sun, said that Middleton will be working together with a group of experts to tackle anti-social behavior and other issues facing the British youth.

Rebecca English, a royal correspondent for the Daily Mail, said that Middleton thinks the problem is as important as climate change. A source told English that the Duchess of Cambridge’s first solo campaign will be a lifelong project.

“She is looking at what she can do over the next five, 10, 15, 20 years. She wants to be able to look back and see what difference has been made. That’s what her position in public life allows her to do,” the source said.

Middleton’s initiative will be launched in the New Year. This is also her first solo campaign because she has only teamed up with Prince William, Prince Harry, and most recently Markle on various causes. The two couples were also the one responsible for putting together the Heads Together campaign that is also centered on mental health issues.

In related news, Middleton reportedly had a private meeting this week even though she is still on maternity leave. Emily Hodgkin, a journalist for Express, said that Middleton and Prince William held the private meeting to say goodbye to one of their palace staff.

Miguel Head, Prince William’s former private secretary, worked for the Duke of Cambridge for six years. This role made Head the oldest member of Prince William and Middleton’s household staff. He will be replaced by senior civil servant Simon Case, who once worked as Theresa May’s private secretary.

Middleton’s maternity leave is set to end in October. The Duchess gave birth to her third child, Prince Louis, on April 23. But even though she’s still on break, Middleton has also been spotted in various public outings such as the Trooping the Colour, Wimbledon, RAF Centenary service, and more.
