"The president of the Republic [of France] plans to appoint Laurent Fabius the head of the Constitutional Council," a communique reads.
Fabius earlier confirmed he would soon step down from his post as the minister of foreign affairs. He reportedly attended a Cabinet meeting for the last time earlier on Wednesday. He gave no reason for his resignation.
The former prime minister, who turns 70 in August, will preside over France’s highest constitutional authority that reviews bills passed by the parliament before they are signed into law by the president.
Fabius’ resignation comes as the French parliament is voting on a package of constitutional changes aimed at boosting security measures after the November 13 terror attacks in Paris.
Earlier on Wednesday, National Assembly lawmakers narrowly approved a controversial proposal that would strip terror convicts with dual nationality of French citizenship.
The draft laws also seek to expand the government’s emergency powers. On Monday, the Assembly endorsed the French government’s plan to enshrine the provision on a state of emergency in the constitution.
