Prince William still misses Queen Elizabeth

Speaking to Eugene Levy for the Apple TV series The Reluctant Traveler, William shared: "I do miss my grandmother and my grandfather.

"It's been quite a bit of change, so you do sort of - you think about them not being here anymore and particularly being in Windsor, for me Windsor is her.

"She loved it here; she spent most of her time here. Showing you around today is very much a case of trying to make sure I'm doing it in the way she'd want you to see it.

"She had her horses here as well, as you can imagine was a big deal for her, so that's why she loved it here."

William paid a heartfelt tribute to his grandmother shortly after she passed away.

The 43-year-old royal admitted that the Queen was "by [his] side" during the happiest and saddest times of his life.

He said in a statement at the time: "On Thursday, the world lost an extraordinary leader, whose commitment to the country, the Realms and the Commonwealth was absolute. So much will be said in the days ahead about the meaning of her historic reign.

"I, however, have lost a grandmother. And while I will grieve her loss, I also feel incredibly grateful. I have had the benefit of The Queen's wisdom and reassurance into my fifth decade. My wife has had twenty years of her guidance and support. My three children have got to spend holidays with her and create memories that will last their whole lives.

"She was by my side at my happiest moments. And she was by my side during the saddest days of my life. I knew this day would come, but it will be some time before the reality of life without Grannie will truly feel real."
