The Duke of Cambridge has paid tribute to his grandfather the Duke of Edinburgh, describing him as an "extraordinary man and part of an extraordinary generation".
Following the death of Prince Philip on Friday 9 April at Windsor Castle, aged 99, Prince William has released a statement.
Both Royal Family members served with the British military.
Prince William served as an officer in the British Army, before undertaking attachments to the Royal Air Force and Royal Navy.
This was until September 2008 when it was announced that he would train to become a full-time pilot with Royal Air Force Search and Rescue (SAR).
Prince Philip had close ties with the Armed Forces throughout his life, including serving during the Second World War to becoming the Royal Navy's Lord High Admiral on his 90th birthday.
In his message, the Duke of Cambridge said: "My grandfather's century of life was defined by service – to his country and Commonwealth, to his wife and Queen, and to our family.
"I feel lucky to have not just had his example to guide me, but his enduring presence well into my own adult life – both through good times and the hardest days.
"I will always be grateful that my wife had so many years to get to know my grandfather and for the kindness he showed her.
"I will never take for granted the special memories my children will always have of their great-grandpa coming to collect them in his carriage and seeing for themselves his infectious sense of adventure as well as his mischievous sense of humour!
"My grandfather was an extraordinary man and part of an extraordinary generation. Catherine and I will continue to do what he would have wanted and will support The Queen in the years ahead. I will miss my Grandpa, but I know he would want us to get on with the job."
