King Charles 75th birthday LIVE updates: Gun salute to be held at the Tower of London as Prince Harry to send well wishes from LA

King Charles will officially launch the Coronation Food Project with the Queen which aims to bridge the gap between food waste and food need.

The royal couple will visit a surplus food distribution centre outside London and meet staff and volunteers to hear about the ways in which food waste can be used for social good.

But the Duke of Sussex and his family will not travel to London where his father is holding a small celebratory gathering at Clarence House this evening.

However, it appears there will be an olive branch from Montecito later today, with a phone this afternoon or evening due to the time difference in California.

Good morning and welcome to our live blog. The King will mark his 75th birthday today by busily highlighting causes close to his heart. Follow along for as we provide updates on all the royal festivities.
