Mclibel trail leaflet was partly work of police spy.

The McLibel case" was an English lawsuit for libel filed by McDonald's Corporation against environmental activists Helen Steel and David Morris (often referred to as "The McLibel Two") over a pamphlet critical of the company. Each of two hearings in English courts found some of the leaflet's contested claims to be libellous and others to be true. The partial nature of the victory, the David-and-Goliath nature of the case, and the drawn-out litigation embarrassed McDonald's.

Now the Guardian reveals  that an undercover police officer posing for years as an environmental activist co-wrote a libellous leaflet that was highly critical of McDonald's, a
They claim that:

The true identity of one of the authors of the "McLibel leaflet" is Bob Lambert, a police officer who used the alias Bob Robinson in his five years infiltrating the London Greenpeace group, is revealed in a new book about undercover policing of protest, published next week.

An undercover police officer posing for years as an environmental activist co-wrote a libellous leaflet that was highly critical of McDonald's, and which led to the longest civil trial in English history, costing the fast-food chain millions of pounds in fees.The true identity of one of the authors of the "McLibel leaflet" is Bob Lambert, a police officer who used the alias Bob Robinson in his five years infiltrating the London Greenpeace group, is revealed in a new book about undercover policing of protest, published next week.

We will probably never know what  the exact contribution Lambert, made to the Leaflet but if it was to be proven that he had written parts of the leaflet that was deemed libellous, can this mean that Lambert's bosses  should be liable for some of the millions of court costs.

I can accept that security forces need to infiltrate  extremist organisation. if they were suspected of endangering public safety, but there's a thin line between this and an agent provocateur.( An agent employed by the police or other entity to act undercover to entice or provoke another person to commit an illegal act or falsely implicate them in partaking in the illegal act)..

We need an investigation to the extent of infiltration into groups who are not a threat to public safety and the role (if any) int these undercover policemen in provoking otherwise law-abiding people into illegal acts.and how productive is it to place someone  in a organisation for years that only controversy was  libelling a  giant corporation , and have an agent revealed as part of that libel. 

We need answers if we a re to believe we live in a free society.
