Coldplay, Emma Thompson and Dermot O'Leary are among the north London stars lined up for the Duke of Cambridge’s Earthshot Prize ceremony at Alexandra Palace.

Prince William launched the environmental prize, which will see winners in five categories each receive £1 million to develop their environmental projects.

He will introduce the ceremony on October 17, while the Duchess of Cambridge will present an award.

The show, to be broadcast on BBC One and globally on Discovery's Facebook page, will feature performances from artists including Sheeran, KSI and Yemi Alade, and Shawn Mendes.

Coldplay, who formed in Camden and release their new album, Music of the Spheres, on October 15, will also perform.

Awards will be handed out by Emma Thompson, Emma Watson, David Oyelowo and Mo Salah.

Sir David Attenborough will speak about the importance of the Earthshot Prize and his optimism in tackling environmental challenges.

Clara Amfo said: “I’m delighted to be co-hosting the inaugural Earthshot Prize ceremony.

“We’re at a critical time in our planet’s history. Our habits are changing slowly but surely. However, we can always learn and, most importantly, do more.”
