Says the Stop Acta London group: "The Anti-Counterfeiting Trade Agreement (ACTA) is a plurilateral agreement for the purpose of establishing international standards for intellectual property rights enforcement.

"The agreement aims to establish an international legal framework for targeting counterfeit goods, generic medicines and copyright infringement on the Internet, and would create a new governing body outside existing forums, such as the World Trade Organization, the World Intellectual Property Organization, or the United Nations."

Massive protests have already erupted in Poland over the sinister agreement.

And on Friday EU official Kader Arif resigned as rapporteur, saying negotiations over the controversial "anti-piracy" agreement "lacked transparency".
