The BBC received seven complaints from women over Wynne Evans' conduct towards them, including one claim he made an inappropriate comment about a pregnant woman's breasts during a Zoom call.
The Mail on Sunday's revelations come just days after opera singer Evans, axed from his BBC Wales breakfast radio show last month, protested on ITV's This Morning that there had been no allegations made against him.
He appeared on the show last Wednesday to tell hosts Cat Deeley and Ben Shephard: 'There has never been any complaints about me. Ever!'
The MoS can instead disclose that BBC Wales staff raised the seven separate grievances between July 2023 and August 2024, including a period after Evans, 53, was approached to appear on last year's Strictly Come Dancing.
Four of the complaints were made before he joined Strictly, raising questions over why the dance show's producers signed him up.
Three more were made after he had been chosen for the show.
A report into his behaviour was prepared in January for a disciplinary hearing which he said he could not attend, citing mental health issues.
The Go Compare frontman's time on Strictly was mired in controversy. The Mail on Sunday told in January how he was filmed using the vile term 'spit roast' – a three-way sex act – to his co-star Jamie Borthwick in relation to professional dancer Janette Manrara during the launch of the Strictly Live Tour.

Wynne Evans appeared on ITV's This Morning last Wednesday to tell hosts Cat Deeley and Ben Shephard: 'There has never been any complaints about me. Ever!'
He apologised and left the tour.
Evans had earlier been caught up in a 'wandering hand' incident with his Strictly dance partner, Katya Jones.
One source said of the BBC Wales complaints: 'Some of the comments he made were awful.
'Imagine making a comment about a pregnant woman's breasts. His behaviour left many women feeling uncomfortable.'
A former colleague, who wants to remain anonymous for fears of career repercussions, told the MoS the complaints were well known among staff at the Welsh broadcaster but 'everyone was afraid to speak out' because Evans was seen as 'untouchable'.
She said: 'That's why he got away with it for so long and why he will get away with it.'
The woman revealed how the father-of-two's inappropriate behaviour 'built up over the years'.
She said: 'At first, he was known as an idiot and a clown but it turned into something more sinister and tipped into being inappropriate and uncomfortable to be around and work with.

'These complaints are real. He is not just someone who has made a few rude jokes. There are women who have made complaints and he was warned time and time again and just kept going.
'The argument that he has of 'Oh, I'm just a product of my time. It's just a joke'... well, those times are gone and you can't act that way, especially if you have been warned about it.'
A BBC spokesman said: 'We take any issues raised with us seriously and we have robust processes in place to deal with them.'
A spokesman for Evans declined to comment.
