The Transatlantic Trade and Investment Partnership (TTIP) is a trade agreement to be negotiated between the European Union and the United States, forming what would be, in effect, the world's biggest trading bloc. 

It could create millions of new jobs and increase trade by billions of dollars - a much needed stimulus for the global economy. But many are not convinced and say it is undemocratic and will only increase the power of big business. 

Free-trade advocates say the TTIP will form a market of 800 million people, create millions of jobs and serve as a counterbalance to growing Asian economic clout.

But political parties and campaigners from across Europe under the banner "Stop TTIP" oppose the deal, saying an accord will undermine European food and environmental laws and give too much power to US corporations.
