The European Union and the US have announced a political agreement that will completely reset the €1.7 trillion ($2 trillion) transatlantic trade relationship.

Discrepancies between the two sides' version of the deal have emerged, and key details of the agreement are yet to be negotiated.

The EU ’s other big concession was cutting its own tariffs on American cars and other industrial goods to zero, as well as giving some farm and fishery products better access to the European market. The liberalisation affects about a quarter of America’s exports to the EU, including cars and footwear; the rest already enter tariff-free.
