Tens of thousands of Tunisians took to the streets late on Saturday to renew their demands that the Islamist-led government step down and end a political deadlock threatening the North African country’s fledgling democracy.

It was the largest protest since Tunisia’s crisis erupted over the killing of an opposition leader in July, increasing pressure on the ruling Ennahda party to make way for a caretaker government before proposed elections.

Waving red and white national flags and pictures of slain opposition leader Mohamed Brahmi, protesters packed streets around a building where a national assembly had been drafting a new constitution until its work was suspended due to unrest.

“It’s over for them, they should leave,” said sports teacher Houssem Ben Hassen at the rally, wrapped in a Tunisian flag.

“We need a government for all Tunisians.”

Divisions between Tunisia’s Islamists and their secular opponents have widened since the uprising that ousted President Zine al-Abidine Ben Ali, a revolt that triggered unrest across the Arab world and toppled rulers in Egypt, Libya and Yemen.

Tunisia’s transition since that revolt has been relatively peaceful, with the moderate Islamist Ennahda party sharing power with smaller secular parties.

But tensions have increased in the nation of 11 million since Brahmi was killed in July, just months after another secular opposition figure was murdered by gunmen who authorities say were tied to radical Islamists.

Drawn-out wrangling over political control, elections and a new constitution now threatens transition and economic growth in a country once seen as the most promising example for the region’s nascent democracies following the “Arab Spring”.

The head of the constituent assembly about to finish drafting the new constitution halted its work after the July opposition leader’s assassination, throwing the country’s transition plan for a caretaker cabinet and elections off track.
