A Downing Street spokesperson said:
The Prime Minister spoke to President Trump this evening. The leaders expressed their serious concern at Turkey’s invasion of north east Syria and the risk of a humanitarian catastrophe in the region.
The two leaders also discussed the tragic death of Harry Dunn. The Prime Minister urged the President to reconsider the US position so the individual involved can return to the UK, cooperate with police and allow Harry’s family to receive justice.
The President said he was fully aware of the case and deeply saddened by what has happened, and he expressed his condolences to Harry’s parents. The leaders agreed to work together to find a way forward as soon as possible.
On trade, the Prime Minister underlined his disappointment at the US announcement of tariffs against UK and EU exports in the Airbus-Boeing dispute, which will harm a number of industries including Scotch Whisky. He pressed the President not to impose the tariffs.
