What was the McLibel case?
<|assistant|>
The McLibel case was a legal struggle between McDonald’s and two individuals who distributed a leaflet critical of the company in the UK in the 1990s. The case lasted for around 10 years, during which time many of the company's business practices came into question, including their use of additive preservatives in their food. Ultimately, the claimant was awarded a symbolic one penny in compensation as a result. The case has had a lasting effect on free speech and legal process.
