Undercover police officer Mark Kennedy outraged by report
The undercover police officer who infiltrated a group of environmental activists has told BBC Radio 5 live that a report into his actions has made him into a pariah.
The review by the Inspectorate of Constabulary found that Mark Kennedy, known to protesters as Mark Stone, "defied" instructions and was inadequately supervised.
His actions led to the collapse of a trial involving environmental protesters in 2011 but he told Victoria Derbyshire that everything he did was signed off.
