The monarch has been attending public events this week on the occasion of his birthday with the aim of honouring community members.

He kicked off celebrations with an afternoon tea party at Highgrove Gardens on November 14 attended by community members who are also celebrating their 75th birthday this year.

Those guests were nominated to attend by their loved ones.

The royal cut a three-tier birthday cake at the event and joked that he'd have to get guests "doggie bags" so they could take it home.
