The BBC has been plunged into a fresh crisis over the Wynne Evans scandal after it emerged the corporation had received complaints from a broadcasting union about his behaviour.

The Broadcasting, Entertainment and Theatre Union (Bectu) said it had ‘previously raised concerns with the BBC about Evans’s inclusion in the Strictly line-up’.

The union’s intervention came after The Mail on Sunday’s exclusive revelations last week that the Welsh singer suggested a vile three-way sex act on his Strictly tour co-star Janette Manrara, using the term ‘spit-roast’.

Bectu said on social media: ‘Is inappropriate behaviour only a problem when it’s caught on camera?’ The BBC refused to comment on the claim, but last night it was reported it would have crisis talks with the Go Compare frontman this week.

Famed for being the jovial moustached Gio Compario in adverts for the insurance comparison site, Evans has since been nicknamed ‘Grope Compare’.

And the MoS can reveal that Evans, 53, who was axed from the Strictly tour after our story, has been accused by former colleagues of making inappropriate ‘jokes’ about women.

Dave Griffiths, who worked for the BBC National Orchestra of Wales with Evans, wrote on Facebook: ‘With the misfortune of sharing the stage with Wynne, this doesn’t come as a surprise.

‘Often his so-called ‘jokes’ backfired leaving audience members and his co-workers stunned.’

Last week, the MoS released explosive footage of the Welsh opera star making the comments about Ms Manrara, 41, at the press launch of the tour.

Evans since said he was ‘taking some time out’ of his BBC Radio Wales show before issuing an apology. The BBC then dropped him from the tour.
