Trump and EU chief Ursula von der Leyen made the deal in Scotland after many months of bargaining, but major details are still pending.

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.
