Buenos Aires: Tens of thousands of supporters jammed Argentina’s most famous square Wednesday night to say goodbye to President Cristina Kirchner, who lauded her government’s achievements while blasting the incoming administration in the same withering tones she aimed at opponents throughout her eight years in office.

As blue and white Argentine flags waved and people cheered on a balmy night, Kirchner gave a speech that was both a recap of her years in power and a clear sign that she does not plan to make things easy for President-elect Mauricio Macri, who will be inaugurated on Thursday.

Kirchner addressed the crowd on Plaza de Mayo in downtown Buenos Aires.

Kirchner talked about “an agenda from the outside being imposed on the region,” apparently referring to the United States and others she sees as enemies of Argentina. During her two terms in power, Kirchner frequently accused other countries of meddling in this South American nation’s affairs, though rarely provided details.

For 12 years, Kirchner, and before her, late husband and predecessor, Nestor Kirchner, dominated the political landscape. The couple rewrote the country’s social contract, spending heavily on social programmes for the poor while passing liberalising laws, such as legalising gay marriage in 2010.

They also aligned Argentina with socialist leaders like the late Venezuelan President Hugo Chavez and Bolivian President Evo Morales, who attended Kirchner’s farewell speech.

“She made me proud to be Argentine for the first time in my life,” said onlooker Pablo Vega. “She defended the interests of the country more than anybody.”

Macri, who ran on free-market ideas, beat Kirchner’s chosen successor by 3 percentage points in a runoff election last month. The close result underscored the deep polarisation in Argentina, and Kirchner has made clear she will continue to be heard, albeit from the sidelines of power.

The 62-year-old, who was barred by the constitution from seeking a third consecutive term, leaves office with approval ratings around 40 per cent, and some have speculated she might try to run again in 2019.

However, just as many Argentines love her, many also loathe her, and the fight over the presidential transition brought out the frustration of detractors.
