Syrian National Council, the main opposition bloc, is holding a two-day meeting in the Turkish city of Istanbul to choose a new president.

Its former head Burhan Ghalioun resigned from his post amid accusations that he was monopolising power.

Al Jazeera's Anita McNaught, reporting from Istanbul, said the SNC has unofficially selected Abdulbaset Sieda, a Kurdish candidate, to follow on from Ghalioun. A vote may not take place if a consensus is confirmed on Sieda.
