A Downing Street spokesperson said:
“The Prime Minister held a telephone call with US President
Donald Trump this evening.
“The Prime Minister began by congratulating the President on the
safe return of three US citizens who had been held in prison in
North Korea.
“The two leaders looked forward to the summit which will take
place between President Trump and Kim Jong-un in Singapore. The
PM said the UK would continue to work with the US to keep up the
pressure on North Korea to denuclearise.
“The Prime Minister and the President condemned the Iranian
rocket attacks against Israeli forces earlier this week, and
strongly supported Israel’s right to defend itself against
Iranian aggression. They agreed on the need for calm on all sides
and on the importance of tackling Iran’s destabilising activity
in the region.
“The Prime Minister reiterated the Government’s position on the
Iran nuclear deal, noting that we and our European partners
remain firmly committed to ensuring the deal is upheld, as the
best way of preventing Iran from developing a nuclear weapon.
“The Prime Minister raised the potential impact of US sanctions
on those firms which are currently conducting business in Iran.
They agreed for talks to take place between our teams.
“Finally, the Prime Minister and the President looked forward to
the President’s visit to the UK in July.”
