The mother of WikiLeaks founder Julian Assange met with Ecuadoran President Rafael Correa on Wednesday to discuss the fate of her son holed up at the country's embassy in Britain.

Assange, 41, is seeking asylum in the South American state to avoid his extradition to Sweden, where he is accused of sexual assault.

During her meeting with Correa, Christine Assange expressed her "concerns and qualms about what could happen to Julian Assange if he is extradited to Sweden by the British government," Foreign Minister Ricardo Patino told reporters.

Assange sought refuge at Ecuador's embassy on 19 June, fearing that he could be extradited to the United States from Sweden to stand trial for espionage, on account of the trove of leaked US diplomatic cables and military logs that were published on his whistleblower website.

The leak represented the biggest breach of US intelligence in history.

Patino has said that Ecuador will respond to Assange's request on 12 August, after the London Olympics.

Correa has often been at odds with Washington and offered Assange asylum in 2010.

He vowed earlier this month that his government would not yield to pressure from Britain, Sweden or the United States in deciding whether to grant Assange asylum.
