Popsugar Celebrity The Royals Prince William and Kate Middleton at Mental Health Summit Will and Kate Return For Their First Joint Royal Outing Together Since Prince Louis's Birth 12 October 2018 by Tori Crowther First Published: 9 October 2018 Image Source: Getty The Duke and Duchess of Cambridge are back at work! Our favourite duo returned via their first joint royal engagement since the birth of Prince Louis in April. Prince William and Kate visited a Global Ministerial Mental Health Summit at County Hall in London on Oct. 9, an initiative that aims to help those with mental health issues from around the world. The duke and duchess were joined by people from over 30 countries in an effort to promote treatments and end worldwide stigma surrounding mental health. William has been busy this past month during his Commonwealth tour of Africa, visiting Namibia, Tanzania, and Kenya in an effort to help end wildlife crime. Meanwhile, Kate ventured out on her first solo engagement after her maternity leave, which was full of adorable moments. We hope to see the couple again at Princess Eugenie's wedding on Oct. 12, but Pippa Middleton is due to give birth the same week, meaning that sister Kate will be on call to help out.
