Argentina swears in new president
Cristina Kirchner takes over from her husband, Nestor
Cristina Fernandez de Kirchner has been sworn in as president of Argentina, six weeks after her convincing win in October's election.
She took over the presidential sash from the outgoing president - her husband, Nestor Kirchner.
Mrs Kirchner becomes Argentina's first elected female head of state.
Many regional leaders were also at the ceremony.
Although both Mr and Mrs Kirchner have repeatedly stressed that she alone will take decisions, the new president said her predecessor will not disappear from the political scene.
"For me and for all Argentines, he will also continue being president," she said.
For the first time ever, Latin America will have two women presidents at the same time, with Mrs Kirchner following the lead of Michelle Bachelet in Chile.
But while many problems remain, the country has seen year-on-year economic growth and relative stability.
