Several crew members working on a Britain’s Got Talent’s Christmas special have tested positive for coronavirus, causing filming to be delayed.

At least three workers for the festive edition of the talent show are affected.

Britain’s Got Talent has halted production and the crew members are self-isolating.

A spokeswoman for the show said on Tuesday: “As a result of a positive Covid-19 result received yesterday we have implemented our protocols and a number of crew members are self-isolating at home.

“As a result, we are unable to continue filming our BGT Christmas Special today and have taken the decision to postpone.

“The safety of all those involved in the show is our number one priority and we follow extensive Covid-19 related procedures to adhere to all government guidelines.”

The Christmas special had not been formally announced, but it has previously been reported that the show will feature some of the show’s most successful acts joining forces to impress the audience.

Hosted by Ant and Dec, this year’s series crowned its latest winner, comedian Jon Courtenay, on Saturday night.
