The French parliament was brought to a halt after a far-right MP shouted “They should go back to Africa” as a black colleague talked about immigration.
Grégoire de Fournas, a member of National Rally (RN), said later his remark had not been aimed at Carlos Marten Bilongo himself but at migrants trying to reach Europe by sea.
Mr Bilongo said he had been born in France and the remark was “shameful”.
Prime Minister Elisabeth Borne said there was “no room for racism”.
The National Assembly’s bureau would meet on Friday and decide on the “necessary sanction”, the liberal politician told reporters.
