President Cristina Fernández criticized sectors of the opposition that are "seeking to privatize again" companies that were recently nationalized by her administration, and said her government has "shut the mouth of neoliberalism."

The president's remarks were made at a ceremony at the Atucha II nuclear plant, where she was inaugurating the installation of a part of the reactor, which is scheduled to become operational in 2011, after decades of delays in the project.

Alongside the president were Buenos Aires Governor Daniel Scioli, who is running for a seat in the Lower House in the upcoming mid-term vote and Planning Minister Julio de Vido.

The Kirchner administration has nationalized several private companies in the past, which it claimed failed to provide a proper service, including Argentina's main water supplier, railway services, a postal company and others.

In her speech, Fernández de Kirchner indirectly referred to City Mayor Mauricio Macri, head of the opposition's PRO-party, claiming that some people "say they want to privatize (airliner) Aerolíneas Argentinas again or they said pensions should be managed by the private sector again."

"They dream of returning to the model of the nineties, because they received profits and income in those years," she said.

Also, President's husband and congressional candidate in Buenos Aires province for the Peronist Victory Front party, Néstor Kirchner, attacked neoliberal politics from the past.

After arriving to the Greater Buenos Aires district of Escobar to lead an act in his party's favour, Former president, Kirchner, said that "due to the need of upward social actions we are having an electoral battle for the June 28 mid term elections, against the past and the ones that sold and bankrupted Argentina".

"I don't care when they attack my own interests they always attack, but I want the people to like me."

"It is necessary to deepen the country's growth" said Kirchner, who also assured that the district will have "the technical school that this people deserve."
