“We start without conditions or limits, our only condition is accepting one another,” said Khalifa bin Ahmed Al-Dhahrani, chairman of the dialogue and also a speaker of parliament.

Inspired by uprisings in Tunisia and Egypt that toppled rulers in the two countries, Bahrain’s opposition took to the streets in February and March to demand political reforms. The government crushed the movement with martial law and help from security forces.

An estimated 30 people died, hundreds were arrested and thousands lost their jobs.

Hoping to defuse tensions, the king lifted martial law a month ago and called for a dialogue to discuss political, economic, social and legal reforms with “all options” on the table.

After lengthy internal debate, Wefaq, the leading opposition group, decided to join the dialogue but threatened to pull out if talks did not move toward greater representation in government. Bahrain has an elected assembly but the ruling Al-Khalifa family appoints cabinet ministers and the upper house.

“The whole of Bahrain will be much better if we have an elected government,” said Wefaq spokesman Khalil Al-Marzouq. Wefaq has complained that it is under-represented and that there are too many people to reach any meaningful consensus.

Dhahrani told participants that any agreed proposals would be taken to the king, who “will pass it on to legal organizations for the necessary implementation.”

The forum has received hundreds of proposals for discussion.

Discussions on Saturday were mostly ceremonial, with a recital from the Qur'an, a speech and presentations. By early afternoon, the main hall was empty and only one sub-group appeared to be in talks in a separate room.

Leading up to the start of the dialogue, the government offered some concessions, including the launch of an investigative panel led by law professor Cherif Bassiouni, an Egyptian-American war crimes expert who is also heading UN inquiry into events in Libya.

King Hamad, in a speech televised on the eve of the talks, said: “It will be a true dialogue in every respect and no section of Bahrain’s wide and diverse society will be ignored.”

Yet hours before the King’s speech, more than 20,000 opposition members crowded the center of the town of Diraz at a Wefaq rally, demanding to be heard and waving Bahraini flags.

“No dialogue with Al-Khalifa” and “Freedom for all prisoners,” they shouted.
