One of the Strictly Come Dancing contestants has claimed that the BBC has banned them from criticising Alesha Dixon’s performance on the show.

The celebrity, who wished to remain anonymous, reportedly showed a briefing document to The Mirror. The document is said to give them answers to press questions about the Alesha/Arlene debacle.

One said: “It was made clear we can’t say what we really think. There is a culture of fear. It’s as if they are trying to brainwash us. It would be funny if so many of us weren’t worried about accidentally saying something inappropriate.”

In response to questions about Arlene’s departure, celebrities are instructed to say: “Arlene’s a good friend and I’m happy she will continue to be part of the Strictly family in her role on The One Show. I’m also looking forward to having Alesha join the series.”

When asked if the show is ageist they must reply: “Age or gender has absolutely nothing to do with the decision to replace Arlene. The age ranges of presenters, judges and contestants show this would not have played a part.”

However, the BBC said: “It is standard practice to give people who will be in interview situations guidance on any questions that may arise but it is ludicrous to suggest this amounts to the BBC banning or gagging anyone.”
