The man who tipped of the loony mob to the location of Nigel Farage and his family on Sunday was Chris Venables, an employee of Medact – a lobbying organisation that has been successful in convincing medical charities to sell off their investments in fossil fuels. Venables’ actions will come as an embarrassment to Medact, who work hard to present themselves as respectable charity made up of doctors and not an activist group made up of hard left green campaigners. Can they afford to keep such a liability on the payroll?
