What is the TTIP?
It's the Transatlantic Trade and Investment Partnership.
TTIP is the biggest free-trade agreement ever, it's being discussed for quite a while now between Europe and the US. The discussions have been critizised for their lack of transparency and a lot of people fear that industry regulations will be lower after the agreement diminishing rights of citizens. Since the outcome will affect 820 million people, we're investigating it.
