Comeback queen: Argentina's fiery "Cristina" stages remarkable return as VP

By Cassandra Garrison

BUENOS AIRES, Oct 28(Reuters) - Argentina's former president Cristina Fernandez de Kirchner, a rockstar politician adored by the poor but feared by big business and investors, is back, although as vice president this time.

The South American country's leader for eight years until 2015, "Cristina", as she is known to fans, returns to the Casa Rosada palace after she and senior running mate Alberto Fernandez scored a decisive victory in Sunday's election.

The return of the fiery Fernandez de Kirchner is a major twist in Argentine politics, turning Latin America's third-largest economy abruptly back towards the left after four years under conservative leader Mauricio Macri.

Dressed in a flowing red outfit and appearing as natural as ever on stage after the victory, Cristina made an impassioned plea for every effort by Macri to stabilize the economy until he leaves office.

"Please.. take all the measures you should take to lighten the dramatic situation that is being experienced in the country's finances. It is your responsibility," she said, before handing the microphone to Alberto Fernandez.

She later posed for selfies on her way out of the arena, as supporters angled to get near her.

By far the biggest name in Argentina's Peronist movement, she stunned everyone in May by announcing she would run as the No. 2 on the presidential ticket of her former chief of staff, amid concerns her divisive image would drive away key centrist voters.

A political powerhouse for more than two decades, her star rose as Argentina's charismatic first lady during the 2003-2007 presidency of her husband, Nestor Kirchner, whom she succeeded, and who died in 2010.

Her second term ended in 2015, amid accusations by critics she was a authoritarian populist who had bankrupted Argentina's economy with welfare spending and graft. She still faces a series of legal cases over graft accusations, which she denies.

She famously refused to attend Macri's inauguration and hand over the presidential baton and sash after the two clashed over where the ceremony should take place.

The surprise tactic of taking the deputy role has worked. Fernandez's star power added glamour to the low-key Peronist ticket and helped tap into popular anger with Macri's administration, as high inflation and an anemic economy have pushed many Argentines into poverty.

Now voters and investors are bracing for Cristina's return. Many believe she will have significant sway behind the scenes, though her party has played this down.
