The Prince of Wales and Duchess of Cornwall will attend the event on the anniversary of the Manchester Arena bombing.

They will be joined by members of the emergency services who were on the scene on the night of the attack.

A minute’s silence was held at a garden party last year for the 22 victims who were killed and those who were injured when a suicide bomb was detonated after an Ariana Grande concert on May 22.

This year’s event will also be attended by more than 6,000 people from charities Charles supports in celebration of his patronage work.
