This Morning's advice guru Vanessa Feltz horrified viewers onThursday's show with an incest comment during her segment where she gives advice to callers.

She was discussing with Ruth Langsford and Eamonn Holmes, who have replaced Phillip Schofield and Holly Willoughby, the issue of blended families.

Eamonn asked Vanessa if the relationship between dads and daughters was a particularly special one, as he thought it was.

Vanessa then brought up the Elektra complex studied by Sigmund Freud, which is theorised to be a girl's psychosexual competition with her mother for possession of her father.

Eamonn asked if fathers and daughters had a special relationship

They were speaking to a caller who complained that her partner treated her son unfairly compared to her daughter.

Eamonn asked: "Could I just say here, fathers and daughters, is there not an excuse to be made there.

"There is a different relationship, there is a special relationship?"

"Let's welcome Sigmund Freud to the show" said Vanessa

"Ah, well, let's welcome Sigmund Freud to the conversation shall we, to talk about the Elektra complex!" exclaimed Vanessa.

"Yes there is a father-daughter thing.

"But if you are trying to make a new family and you happen to be the mother of the son that isn't being treated kindly and sweetly, I don't know how much allowance for fathers and daughters you're going to make."

Ruth just looked at Eamonn, who was laughing, and later told Vanessa he was just trying to wind them up.

One astonished viewer tweeted: "'Let's welcome Sigmund Freud to the programme.' Excellent slapdown by Vanessa on Eammon. #ThisMorning."

"Was that a dig?" pondered another.

Another remarked: "The Oedipus complex? Sorry, but I draw a line at incest! #ThisMorning."
