The BBC sport host will voice over Charles’s and Queen Camilla’s ceremonial route, while Kirsty anchors the show from a studio at Buckingham Palace. News at Ten presenter Huw will provide commentary as guests arrive at Westminster Abbey, while former marine JJ Chalmers will interview the military parade participants.
Sophie Raworth will interview guests outside the Abbey and Anita Rani will speak to crowds gathered along the route.
The broadcaster will follow up the ceremony on Saturday May 6 with TV coverage of the Coronation Concert at Windsor Castle the following day.
Kirsty will be the main anchor again, while Radio 1’s Clara Amfo and dancer Jordan Banjo will be backstage with artists thought to include Take That and Lionel Ritchie.
More than 20,000 members of the public are expected to attend – including volunteers from the King and Queen’s favourite charities.
Zoe Ball and Dermot O’Leary will be among the crowd to capture the atmosphere for Radio 2 listeners.
Kirsty said: “Ceremony, spectacle and a right royal celebration – it’s got all the ingredients of a weekend worth watching.”
Huw said: “Few broadcasters have the privilege of working on a Coronation and I’m delighted to be involved.”
Zoe added: “What a thrill it is to be part of Radio 2’s coverage of the Coronation concert – speaking to all the stars before they take to the stage for what will be such a fabulous celebration.”
BBC Director-General Tim Davie said: “We will be delivering the full glory of the Coronation with all the quality, ambition and excellence that our teams are globally renowned for.”
