In its judgement, the Employment Tribunal blamed Mr McCririck's on-screen persona for his demise.
All the evidence is that Mr McCririck's pantomime persona, as demonstrated on the celebrity television appearances, and his persona when appearing on Channel 4 Racing, together with his self-described bigoted and male chauvinist views were clearly unpalatable to a wider potential audience.
The tribunal is satisfied that the respondent had the legitimate aim of attracting a wider audience to horseracing.
Racing pundit John McCririck has given his reaction to losing his age discrimination case against Channel 4 today.
This is an historic setback for all employees in their 30s to their 70s.
After such a landmark judicial verdict, my failed legal action ensures that anonymous suits and skirts, who control the media, numerous other businesses and the public sector, will now enjoy complete freedom to replace older employees whatever their unimpaired ability and merit.
I have let them all down along with my wife, the Booby, my legal team, friends, colleagues and countless members of the public who supported me throughout. My grateful thanks and apologies to every one of them.
