Tunisia holds first post-revolution presidential poll

Tunisians have gone to the polls to pick their first directly-elected president.

More than 25 candidates are in the race, but incumbent Moncef Marzouki and anti-Islamist leader Beji Caid Essebsi are widely seen as the favourites.

The poll forms part of a political transition after the revolution that ousted Zine al-Abidine Ben Ali.
