A number of senior Times editorial staff, including editor John Witherow, are expected to appear in Scotland to defend the title against claims of a sexist newsroom culture that discriminates against transgender people.

Former Scotland night editor Katherine O’Donnell is suing Times Newspapers, which publishes the Times and Sunday Times, for unfair dismissal and discrimination at Edinburgh Employment Tribunal.

Her case is backed by a number of ex-Times newsdesk and production staff.
