The Duchess of Sussex has sent a personal video message in memory of an animal behaviourist friend to mark the naming of a new rescue wing in his honour.

Meghan paid tribute to dog trainer Oli Juste, who introduced her to the Mayhew animal charity, leading to her becoming its patron for three years.

The recording of the duchess was played to guests including actors Nigel Harman, Rula Lenska, Beatie Edney and Laura Aikman at the unveiling of the Oli Juste Wing at Mayhew’s centre in north London on Wednesday.

Mr Juste died suddenly in January 2022, and Mayhew said a “generous” donation made by his “dear friend” Meghan through her Archewell Foundation, to help continue his legacy, had made the new refurbished kennels possible.

The duchess said in her message: “A heartfelt thank you to the wonderful team at Mayhew who have worked tirelessly to bring this dream to life.

“It was so important to find a way to celebrate Oli’s memory in a manner that he would have loved.

“Mayhew is a beacon of hope for those in need and a shining example of what can be achieved when we work together.”

A statement on Meghan’s sussex.com website recounted the duchess’ bond with Mr Juste, saying: “They shared many things throughout their friendship, among which was a deep commitment to animal welfare and a love of rescue dogs.”

It added: “The Oli Juste Wing is a testament to his unwavering love and commitment to our furry friends, and will improve the lives of countless animals, reminding us all of the power of compassion, connection, and care.”

The duchess has adopted a number of rescue dogs over the years including a Guy, a beagle, and a black Labrador called Pula.

Mr Juste and his fiance Rob helped care for Guy when Meghan moved to the UK and the dog was recovering from an accident.

Meghan wrote in 2022 that she was left “heartbroken” by Mr Juste’s death.
