Ecuador's Foreign Minister Ricardo Patino has proposed that WikiLeaks founder Julian Assange be transferred from London to Sweden, where he would remain under Quito's protection.

Assange took shelter in the Ecuadorian embassy in London in June after exhausting all appeals against extradition from Britain to Sweden, where he is wanted for questioning over sexual assault allegations. Ecuador has granted him diplomatic asylum.

The 41-year-old Australian fears Sweden will hand him over to the United States, where he could face prosecution over the release of a vast cache of leaked Iraq and Afghanistan war reports and diplomatic cables.

Patino hinted to "new" developments in the Swedish case, saying "several elements of proof have been dismissed," though he declined to provide further details.

He stressed that the best option, in Ecuador's view, would be for Britain to grant Assange safe passage.

On the margins of next week's United Nations General Assembly in New York, Patino plans to discuss Assange's case with his British counterpart William Hague.
