Upon their arrival at London's Banqueting House, the royal couple appeared to be in great spirits. As ever, Kate - who welcomed her third child, Prince Louis, in April - looked picture perfect in her stunning aqua green floor-length gown by Jenny Packham, which she styled further with chic heels and dazzling jewellery. At the reception, William and Kate will meet with the award nominees, Tusk supporters and sponsors. The Duke will also present three awards before delivering a short speech.

It's a special night for Prince William, who became Royal Patron of Tusk in December 2005. The Duke, 36, has actively supported the charity's work both privately and publicly on many occasions and recently visited Tusk projects in Namibia and Tanzania. For almost thirty years, Tusk has pioneered successful conservation action in Africa by protecting wildlife, empowering communities and advancing the frontline in the fight against the illegal wildlife trade. The annual Tusk Conservation Awards celebrate the achievements of extraordinary people, whose work protecting Africa’s natural heritage might otherwise go unnoticed outside their fields.

Last month, William paid a solo visit to Namibia, Tanzania and Kenya to help end cruelty against the continent’s beautiful wildlife with the campaign #EndWildlifeCrime. Throughout his week-long trip, the royal joined a group in a rhino search, met with members of Save the Rhino Trust Namibia and learned all about the local efforts to protect the animals. “I was staggered by the beauty and sheer remoteness of this incredible landscape," he said in Namibia. "And I was humbled by the dedication of the rangers who protect the unique population of desert rhino from poachers."

The Duke has always been a major supporter of this particular charity - he attended the awards ceremony back in 2016 and 2015.

For the event, Kate wore her favourite green floor-length Jenny Packham gown. With her brunette tresses worn in luscious waves, the royal highlighted her pretty facial features with muted tones of makeup.

In 2012, Kate previously wore this gown to a gala event at the Royal Albert Hall to mark the countdown to the London Olympic Games.

Kate's dress features gorgeous lace back detailing and a pleated skirt.
