[BBC] Former President Mahmoud Ahmadinejad has registered as a candidate in Iran's presidential election, despite being told not to by the Supreme Leader.Mr Ahmadinejad, a hardliner who served two terms between 2005 and 2013, filed paperwork for the 19 May poll at the interior ministry in Tehran.
Last year, Ayatollah Ali Khamenei warned him that such a move was "not in his interest and that of the country".
But Mr Ahmadinejad told reporters on Tuesday that had been "just advice".
Associated Press journalists who witnessed Mr Ahmadinejad register on Tuesday said election officials were "stunned" when he submitted the paperwork.
