Classic FM presenters Myleene Klass and Aled Jones are hosting the Regent Street Lights switch on this Sunday.
The event will see special guests including Darcey Bussell, Laura Wright and Alison Balsom.
Darcey, the Strictly Come Dancing judge and former prima ballerina, will pull the switch at approximately 6.30pm to launch Christmas across the capital.
Darcey said: “I am honoured to be invited to switch on the world famous Regent Street Lights. It promises to be a spectacular evening as we celebrate the start of Christmas in London. A time to get together and to think of others.”
Myleene Klass added: “Classic FM is the home of Christmas music, so Aled and I are really looking forward to officially launching the festive season on one of the world’s most famous shopping streets. London, let the countdown begin!”
Annie Walker, Director of the Regent Street Association said: ” We’re delighted to announce our new partnership with Classic FM, Jo Malone London and ACT Lighting Design for the Regent Street Christmas Lights. The Regent Street annual switch-on is the highlight of our year, marking the start of the festive season in the West End. It’s been an exciting year with fantastic retailers joining the shopping street, including fragrance brand Jo Malone London and more flagship stores set to open in 2016.”
