A Downing Street spokesperson said:
The Prime Minister spoke to President Macron of France this afternoon.
On Iran, they both expressed their firm commitment to the nuclear deal, and discussed President Trump’s decision last week not to recertify it.
They agreed to continue to work closely together to ensure the deal is properly enforced, and to push back on Iran’s destabilising activity in the region, including its ballistic missile programme.
They said they would discuss next steps in the margins of the European Council in Brussels later this week.
On Brexit, they discussed progress in the negotiations and looked ahead to this week’s Council.
They also spoke about the strong UK-France relationship, and agreed to continue building on our bilateral partnership in a range of areas.
