The special programme, which also features his brother Prince Harry, his father Prince Charles and uncle Prince Andrew, was originally arranged to mark the Duke's 100th birthday in June, two months before his centenary.
Interviews with the various royals were recorded both before and after Prince Philip's death, with Prince Harry's tributes filmed in California, where he lives with wife Meghan Markle and their two children Archie and Lilibet.

Kate Middleton, 39, a keen photographer, started her campaign during the first lockdown last year to ask the public to submit images which captured the period.
The result was a photography book, Hold Still: A Portrait of Our Nation in 2020, which featured 100 final 'poignant and personal' portraits selected from 31,000 entrants and quickly became a bestseller upon its release in May.
