Judge Motsi Mabuse has had to withdraw from Saturday's edition of Strictly Come Dancing due to UK covid guidelines.

She was contacted by NHS Test and Trace and, as a result, will be replaced on the BBC One show by Cynthia Erivo.

A statement from Strictly Come Dancing said: "We can confirm Motsi Mabuse will not be taking part in Strictly Come Dancing this weekend.

"We are delighted that Cynthia Erivo will be joining us as a guest judge again, joining Craig Revel Horwood, Anton Du Beke and head judge Shirley Ballas on the judging panel.

"We look forward to having Motsi back with us next weekend."

The Germany-based Motsi Mabuse said she would normally be exempt from isolation because she is double vaccinated and has had a booster but her German vaccines are not recognised in the UK.

She said in a statement on Instagram: "I must follow UK Government guidance and can only return after 30 November 2021 to UK.

"Our health is the most important thing and luckily I have been tested multiple times this week and am negative.

"I am healthy, I am with my family, that's what matters."
