He's the longest-running judge on BBC One's biggest show.
Craig Revel Horwood has been a mainstay on Strictly Come Dancing since its first series and is known for his withering putdowns, glances, and 'fab-u-lous' praises.
In the 2021 series, Craig has been joined once again by Strictly's current head judge Shirley Ballas and Motsi Mabuse.
In a change to the lineup this year in light of Bruno Tonioli uncertain travel rules from the US, long-running Strictly professional dancer Anton Du Beke stepped up to the panel after enjoying a brief stint in the 2020 series.
However, in a change to the panel on the show this Saturday (20th November), Craig is absent and has been replaced by award-winning actress-performer Cynthia Erivo.
