I didn't see this programme because I don't like Esther Rantzen.
I wonder if she pursued the subject of the grief felt by abandoned wives and children when their husband/father leaves them for another woman?
I have never forgotten an interview with Desmond Wilcox's daughter, given after her mother died, in which she described how Esther Rantzen pursued her father relentlessly, how her mother was devastated, and how she and her siblings were forced into publicity shoots with her stepmother to show Esther at the heart of her (Wilcox's) loving family, to the great distress of her mother. She did not want her private life discussed or to be the object of pity, so her daughter waited until her mother had died before she presented the other side of the picture.
