The Duke of Edinburgh retired nearly three years ago after decades of royal service.

Philip, 99, has kept himself busy, holding audiences, attending royal weddings and meeting new additions to the family.

He survived a car crash early in 2019, emerging unscathed when his vehicle flipped over after colliding with another carrying two women and a baby.

The duke has been staying at Windsor Castle with the Queen for the past 18 weeks in HMS Bubble – the nickname given to the couple’s reduced household of devoted staff during lockdown.

As Philip briefly steps out of retirement to carry out a rare official public engagement on Wednesday, here is a look at what he has been up to over the past year and a half.
