The grandsons of the late Prince Philip, Prince William and Prince Harry, have both issued statements, paying warm tributes to their grandfather who passed away on Friday aged 99.

The long-serving Queen’s consort and patriarch of the Royal family was hailed as a man of service, honour and great humour.

The eldest of the two Princes is second in line to the throne and the younger recently moved to California after stepping down from royal duties.

Prince Harry returns to UK ahead of the Duke’s funeral:

William, the Duke of Cambridge, says in a statement that his grandfather’s century of life was defined by service to his country and the Commonwealth and that he felt lucky to have had Prince Philip’s enduring presence into his adult life.

Harry, the Duke of Sussex who has since travelled back to the United Kingdom ahead of the funeral on Saturday, released a separate statement calling his late grandfather someone who was authentically himself, with a seriously sharp wit but someone who was simply grandpa; master of the barbecue, legend of banter and cheeky right ’til the end.

Prince Philip’s funeral will be a private ceremony at Windsor Castle.

Prince Philip’s funeral service will be held at St George’s Chapel:
