The televised show will be on 7 May, the day after King Charles is crowned at Westminster Abbey.

The BBC has promised the line-up will feature "musical icons and contemporary stars".

There will be 5,000 pairs of tickets in the ballot, which will open at 07:00 on Friday and close on 28 February.

They would be allocated based on the geographical spread of the UK population, the BBC said.

'Momentous occasion'

The castle's east lawn would see "a world-class orchestra play interpretations of musical favourites fronted by fantastic entertainers, alongside performers from the world of dance and the arts", the BBC said.

It "will also feature a selection of spoken-word sequences delivered by stars of stage and screen", a statement added.

More tickets will be made available to a range of charities and the event will be broadcast on BBC TV, radio and online.

BBC chief content officer Charlotte Moore said: "The coronation concert on the BBC will bring the nation together to mark this momentous occasion and we are thrilled to be able to offer the public the opportunity to be part of the event at Windsor Castle through a national ballot, as well as providing audiences with exclusive coverage across TV and radio."
