Ms Palmer, a partner at Clerkenwell-based Leigh Day & Co, has been contacted by women across Europe since the tribunal. "One woman said she felt a lot safer now. I hope employers will take notice," she said. The lawyer, who spent 14 months preparing O'Reilly's case, said: "Litigation is not easy. It is expensive and time consuming and may not be good for your career. But Miriam felt she had nothing to lose." The campaign is backed by one of Ms Palmer's neighbours, TV actress Kate Buffery, who has fought for more roles for older women. The former star of Wish Me Luck has collected more than 8,000 signatures for an online petition on behalf of the actors' union Equity.
