The current Tunisia government of Youssef Chahed has led to a serious political crisis, the Nidaa Tounes party said.
The party, which is taking over the presidency, parliament and government, expressed its "full readiness to engage in any political responsibility coming from any position, according to its consistent assessment of national interest and its absolute refusal to be a tool to strike the social and political consensus".
The movement criticised what it described as "a focused campaign targeting the role of the President of the Republic as a patron of political and social consensus and a reference to popular electoral and constitutional legitimacy."
The movement called on its parliamentary bloc to meet today, announcing that it would keep its meeting open in order to take the necessary decisions in light of what will lead to developments and discussions with political and social parties.
The Tunisian president, who is currently in Paris, announced on Monday the suspension of the work of the Carthage II Document in the light of disagreements over a number of clauses.Chahed was appointed prime minister by President Beji Caid Essebsi in August 2016 and tasked with setting up a government.
