A minister in the government of Argentina's Buenos Aires province, the country's largest, has sparked controversy by suggesting that it could seek to become independent.

Jorge D’Onofrio, who is transport minister in the province's left-wing Peronist administration, said in a radio interview that if it were a nation in its own right, it would have the "biggest GDP in Latin America".

He described the policies of Argentina's national government, led by right-wing libertarian President Javier Milei, as "madness" and accused him of destroying the nation.
