Janette Manrara, Nadia Bychkova and Dianne Buswell have praised Dincwear, who make leggings and leotards, on their social media channels

Strictly Come Dancing stars have quick-stepped into a row over whether they have plugged a dance clothes brand against the rules.

Janette Manrara, Nadia Bychkova and Dianne Buswell have praised Dincwear, who make leggings and leotards, on their social media channels.

A source at the Beeb said they would “look into it and react accordingly” if its stars have crossed BBC lines by receiving “free or reduced cost products” in return for mentions.

Third parties are also not allowed to cash in on BBC programmes.

But the company boasts on its website how “12 of the pro-stars are seen rehearsing in Dincwear” – with several pictures of Strictly stars in their outfits, some while filming BBC rehearsals.

BBC sources said they would ask the company to remove Strictly references. It is not known if the dancers knew Strictly was referred to on the website.

In one of her posts Dianne, in a Dincwear hoodie, uses the firm’s Instagram handle and adds a love-heart.

Nadiya says in a separate post ­“absolutely love my dincwear leggings”, with a link to the brand.

Janette, now hosting Strictly spin-off It Takes Two, posted an Instagram story of her in a Dincwear outfit, saying: “My newest leotard! Love it,” with a brand plug.

Dincwear has other links to Strictly too.

Dancer Karen Hauer this year struck up a commercial deal with Dincwear, creating her own branded KH leotard.

BBC insiders say no rules were broken in this instance. Others who feature in “Strictly stars in Dincwear” on the firm’s website include Katya Jones, Amy Dowden, Giovanni Pernici and Graziano Di Prima.
