In 1990, activists from a small group known as London Greenpeace (no connection to the international group Greenpeace) distributed leaflets entitled "What's wrong with McDonald's?", criticizing its environmental, health, and labor record. The corporation wrote to the group demanding they desist and apologize, and, when two of the activists refused to back down, sued them for libel leading to the "McLibel case", one of the longest cases in English civil law. A documentary film of the McLibel Trial has been shown in several countries.
