Protesters take part in demonstration against Transatlantic Trade and Investment Partnership (TTIP) in Madrid on October 11, 2014. European and US negotiators have been in talks for more than a year to create the world’s biggest free-trade and investment agreement, the proposed TTIP. But the ambitious pact has raised an array of concerns about issues including whether it will override local laws, and sharp accusations that negotiations are taking place behind closed doors to protect the advance of corporate interests.
