Chavez in Brazil on first foreign trip in a year

The Venezuelan president, Hugo Chavez, has travelled to Brazil on his first official trip abroad since being diagnosed with cancer over a year ago.
Chavez will take part in a regional summit where Venezuela will become a member of the Mercosur trading bloc.
He says he is now healthy and fit to run for a third term in October's elections.
He kept a low profile during his cancer treatment, travelling only to Cuba for medical reasons.
The BBC's Sarah Grainger in Caracas says Chavez has increased his public appearances recently.
"This trip is the latest sign that the president is cranking up his election campaign," she says.
On his 58th birthday on Saturday, he spoke for several hours at a rally in one of the poorest neighbourhoods in Caracas, dancing, singing and sharing a birthday cake with party supporters.
Many doubted that Chavez would be able to recover from cancer, details of which have remained secret.
But he always maintained that he would be ready to run in October's vote.
His campaign has focused not only on social and economic issues but also on reassuring voters that he is fully recovered.
