European Commission President Ursula von der Leyen will meet President Donald Trump on Sunday in a bid to reach a trade agreement ahead of Friday’s deadline, at which point 30% tariffs on the bloc’s exports to the US are otherwise due to kick in.

The stakes for the talks, scheduled for 4:30 p.m. local time at Trump’s golf resort in Turnberry, western Scotland, could hardly be higher for von der Leyen. Yet after months of talks and shuttle diplomacy, finalizing a deal hinges mostly on Trump.
