Thirty-seven heads of government have confirmed their participation in the troubled Commonwealth Summit to be hosted by Sri Lanka next month, a minister said today.

"Thirty-seven heads of government have confirmed participation, which is more than at (the last Commonwealth Summit in) Perth," Information Minister Keheliya Rambukwella told reporters.

The Commonwealth Heads of Government Meeting will be held here during November 15-17.

Prime Minister Manmohan Singh's participation is uncertain.
