Outgoing prime minister Theresa May and Johnson’s leadership rival Jeremy Hunt also tweeted their congratulations to the U.K’s new leader, who will officially become prime minister on Wednesday (July 24).
Iranian foreign affairs minister Javad Zarif congratulated Johnson, but also took the opportunity to condemn the May government’s seizure of Iranian oil.
Johnson has agreed with Trump’s statement that Iran must be constrained. Speaking during Conservative party hustings in June, Johnson said that vigilance was key, as Iran’s government “are bent on all sorts of mischief in the region.”
