Hassan Rouhani wins Iranian presidential election

Reformist-backed cleric Hassan Rouhani has won Iran's presidential election, securing just over 50% of the vote and so avoiding the need for a run-off.

Turnout was estimated at 72.2% among the 50 million Iranians who were eligible to vote to choose a successor to Mahmoud Ahmadinejad.

Supreme Leader Ayatollah Ali Khamenei is scheduled to ratify the vote on 3 August.
