The BBC story may need some clarification.
There were two programmes, one a long-running show from the pre-internet days and another more recent one on a digital channel. They both involved reading out emails, and previously letters, from viewers. One was about anything on television and the other was specifically about the news. The presenter of the news programme, who was female, was paid less than the presenter of the television-feedback programme, who was male.
The courts decided that both should be paid the same and that the reason they were not was because of their difference in sex, despite the claims of the BBC's lawyers to the contrary. Incidentally, the male presenter of the BBC's television-feedback programme was paid the same as his predecessor, who was a woman and who had negotiated a higher salary than her predecessor, who was a man.
