Senegal's National Assembly passed a bill revising the balance of power between the country's executive and parliament on Monday, prompting the president to announce a national referendum on the matter.
The bill was passed by an overwhelming majority in a tense atmosphere marked by heated exchanges, an opposition boycott and scuffles outside the building during which police used tear gas, AFP journalists saw.
The Pastef party, led by President Bassirou Diomaye Faye's rival and former prime minister Ousmane Sonko, proposed the measure.
Faye fired Sonko as prime minister in May and Sonko was swiftly named speaker of the National Assembly, which is controlled by Pastef.
The constitutional amendment faces criticism from the opposition and various civil society organisations.
