The only moderate candidate in the election, former central bank governor Abdolnasser Hemmati, is one of those who sent his congratulations to state media in Iran.

At the same time, incumbent President Hassan Rouhani states that the election has a winner, without telling who it is.

In a televised speech, outgoing President Hassan Rouhani congratulated "the people's elected president"

 - As it has not yet been officially announced, I will delay the official congratulations.

But it is clear who got the votes, Rouhani said.
