Argentina's center-right government managed Tuesday to push through pension overhauls that have prompted several violent protests, with critics saying the changes will weigh heaviest on the poorest sectors of society.

Members of the governing "Cambiemos", or Change, coalition won 128 votes in favor of the bill, with 116 voting against and two abstaining.

On Monday clashes erupted between police and protestors opposed to the measures near the country's congress building in Buenos Aires, with demonstrators continuing to bang pots and pans in protest late into the night.

President Mauricio Macri, in power since 2015, has been trying to limit pension payouts to lower the country's deficit, which is estimated at five percent of GDP.
