Tehran - Moderate cleric Mehdi Karroubi became the first candidate to officially declare his nomination Sunday for next June's presidential elections to challenge Iranian President Mahmoud Ahmadinejad.
The 71-year-old cleric is head of the moderate opposition party Etemad Melli (National Trust) and the party's choice run in the June 12 elections.
"It will be quite difficult but I am still ready to take the challenge for changing the political status quo," Karroubi said in a press conference in Tehran.
The cleric referred to the president's economic and foreign policies as the main problems of the current administration which should be amended.
