Argentine leader Cristina Fernandez seeks re-election

A win for Ms Fernandez in Sunday's election would represent a dramatic change of fortunes for her

Argentines are going to the polls in elections that incumbent president Cristina Fernandez looks set to win.

Ms Fernandez won more than 50% of the vote in a primary in August, which observers say is a good indicator for Sunday's final result.
She has presided over strong economic growth and introduced popular social policies.
The sudden death of her husband, former president Nestor Kirchner, a year ago brought her a wave of support.
Her critics say she has also benefited from a weak and fragmented opposition in this election.
Ms Fernandez is expected to score more than 50% of the vote, avoiding the need for a run off with her rivals, the nearest of which is Socialist candidate Hermes Binner.
Nearly 30 million voters are also choosing who will fill 130 seats in the lower house of congress, 24 senate seats and nine governor's offices as well as hundreds of local seats.
High inflation The BBC's Vladimir Hernandez in Buenos Aires says some opinion polls suggest Ms Fernandez might be on course for a historic landslide victory.
If so, it would mark a dramatic change of fortune for the 58-year-old, he adds.

Following her election in 2007, Ms Fernandez's public support quickly plummeted to around 20% after rows with farmers and media groups over of the introduction of exports quotas.

It was often suggested, during her early years in office, that it was her husband who was really running the country.
Nestor Kirchner was president from 2003 to 2007 and stood aside to let his wife run for office to succeed him.
He was widely expected to run again for the presidency in 2011 until his sudden death from a heart attack last October.
Political analysts say Ms Fernandez's current popularity is mostly due to the health of the economy. Last year, Argentina was among the fastest growing economies in the world, mainly due to the export of commodities, our correspondent reports.
She has also carried out social programmes - such as benefits for three million of the country's poorest children and free laptops for those in deprived areas - which have proved extremely popular.
But her critics accuse her of pursuing populist policies, and say these kinds of programmes are unsustainable if the funding is dependent on commodity prices.
And one of Ms Fernandez's key challenges if she wins Sunday's election is to tackle inflation, which is now the second highest in Latin America, behind Venezuela.
