LONDON, Oct 10 (Reuters) - Prime Minister Theresa May reaffirmed Britain's commitment to a 2015 Iran nuclear deal on Tuesday in a telephone conversation with U.S. President Donald Trump ahead of a key U.S. decision on whether Tehran has stuck to the terms of the pact.
Trump has cast doubt on the future of the Joint Comprehensive Plan of Action (JCPOA), which sought to curb Iran's nuclear programme in return for lifting most Western economic sanctions.
A senior U.S. administration official said last week that Trump - who has criticised the pact as an "embarrassment" and "the worst deal ever negotiated," - was expected to decertify Iran's compliance ahead of an Oct. 15 deadline. (prime minister) reaffirmed the UK's strong commitment to the deal alongside our European partners, saying it was vitally important for regional security," an emailed statement from May's office said.
"(The prime minister) stressed that it was important that the deal was carefully monitored and properly enforced."
Earlier, the White House said Trump would make an announcement later this week on an "overall Iran strategy," including whether to decertify the nuclear deal. office said she agreed with Trump that their teams should remain in contact ahead of the decision on recertification.
