The audience, made up of the inspirational children and their families, and nurses, doctors and carers, as well as celebrities, bowed their heads.

In a change of proceedings, given the circumstances, the winning children then took to the stage to receive their awards ahead of being joined by A-listers including, Leigh-Ann Pinnock, Laura Hamilton, Frankie Bridge and Dick and Dom for a photo to mark the occasion.

As part of their European tour, the Duke and Duchess of Sussex were due to make an appearance at Thursday's ceremony to commemorate the most inspiring children and young people currently battling serious or complex medical issues.

Harry has been a patron of the charity since 2007 and always gives an emotional speech at the ceremony.

However on Thursday morning, Prince Harry and Meghan Markle announced they had canceled their appearance and the Duke would be joining his family, inducing Prince William and Prince Charles at Balmoral to stay close to the matriarch.

The Queen passed away later that day.
