Diversity will be joined by a line up of acts and famous faces on the show.
The heroes behind the uniforms will be celebrated and honoured in one-off festive show on ITV called 'A Night For The Emergency Services’.
Presented by Ashley Banjo and Diversity, the show will feature talented members of the emergency services performing alongside special celebrity guests including Michael Ball and Alfie Boe, X Factor's Leona Lewis and current Britain's Got Talent winners Tokio Myers.
Following a year beset with national tragedy, the appreciation for the emergency services has never been higher. This show aims to both celebrate the incredible work they do, and thank them - the show’s audience will be made up solely of emergency service staff.
As well as honouring their dedication and the life-risking work they do, the emergency services will also get to showcase some of their incredible talents performing on the show in orchestras, choirs, also singers, dancers and even a magician.
Host Ashley Banjo said: “Our emergency services are incredible. They do so much for us and it’s fantastic to not only put on a show for them, but to perform alongside some of the talented people within the emergency services to show the nation’s thanks and appreciation for the work they do.
"It’s going to be a great night!"
Produced by ITV Studios, A Night For The Emergency Services airs TONIGHT on ITV on Wednesday, December 20 at 9PM.
