Officials have dropped charges against pharmacies alleged to have advised people to take homeopathic remedies to protect them against malaria instead of anti-malarial drugs.
The General Pharmaceutical Council's decision has been described as "shabby and irresponsible" by some who helped bring the case against the pharmacies. Charges were bought after an undercover investigation by campaigning group Sense about Science and BBC Newsnight. Experts advocate anti-malaria drugs.
Speaking about the latest decision, Tracey Brown, director of Sense about Science said "we may as well have no regulation of pharmacists at all".
