Tunisian President Moncef Marzouki's secular Congress for the Republic (CPR) will remain part of the coalition government, pending the resignation of key ministers from the ruling Islamist Ennahda party.

"We have decided to freeze our decision to withdraw our ministers from the government, but if in one week we don't see any changes, we will quit the government," AFP quoted CPR chief Mohamed Abbou as saying on Monday (February 11th).

Prime Minister Hamadi Jebali also reiterated Monday that he had "no other choice but to form a transitional, non-partisan government".

"The situation is difficult and urgent, and there is a danger of violence," Jebali told Le Monde. "I cannot wait," he added.

Jebali on Saturday threatened to quit, warning of chaos unless a new Tunisia government were formed.

The killing of opposition leader Chokri Belaid last week has triggered the greatest political crisis in the country since the revolution.
