The boss of a major recycling plant went incognito to find out first hand what his staff thought of his business.

Colin Drummond, chief executive of Viridor, masqueraded as an unemployed worker called John Roy as part of the Channel 4 series Undercover Boss.

Among the sites he toured was the Materials Recycling Facility in Ford, near Arundel, which his company runs for West Sussex County Council.

Mr Drummond, 59, said he gained some valuable insights on where potential improvements can be made as well as meeting unsung heroes among his staff.

Undercover Boss is broadcast on Channel 4 tonight at 9pm.
