Kate Middleton, the Duchess of Cambridge, attended the annual National Review of Queen's Scouts held at Windsor Castle in Berkshire.

The 31-year-old pregnant royal showed off her baby bump in a light green Mulberry coat, with floral-inspired postman's lock detailing, which featured oversized pockets, frayed edging and a soft round collar. She combined that with a cappuccino-coloured Whiteley hat, nude LK Bennett Sledge shoes and Kiki McDonough green amethyst earrings.

Kate, who is almost seven months pregnant, interacted with young people from around the UK and the Commonwealth, all of whom received the Queen's Scout Award. To earn this accolade, youngsters must complete a range of activities including camping, exploring and taking part in outdoor activities.

"It's great that so many adults are joining the Scouts, and I am sure the increase has had much to do with the Duchess of Cambridge becoming a Scout volunteer last year," Chief Scout Bear Grylls said, "She is an incredible role model and she helps us show that Scouting's not just for boys. She's also such a generous volunteer and everyone is so excited to have her in the Scouting family."

Kate Middleton also met Scouts who received special gallantry awards, including Lee Craven, who pulled a friend out of an icy canal last year.

"I hooked my feet under a tree stump and tried to reach for his hand," the 17-year-old said, "It was pitch black but I managed to pull him to the side to safety. It was quite easy because of the adrenalin."

The Duchess is a strong supporter of the Scouts and regularly volunteers with a Cub Scout group. She also joined in a volunteer training event at the Scout Association's centre in Cumbria, back in March.
