British authorities have demanded that WikiLeaks founder Julian Assange present himself at Belgravia police station at 11.30am on Friday. According to the Guardian, "This is standard practice in extradition cases and is the first step in the removal process," and "Failing to surrender would be a further breach of conditions and he is liable to arrest." But if he complies, police may arrest him immediately, because he has breached the terms of his bail.

Reuters reports:

On Thursday, British police summoned Assange to a London police station, demanding he leave the embassy. But Assange later told BBC television in a telephone interview: "Our advice is that asylum law both internationally and domestically in the UK takes precedence to extradition law, so the answer is almost certainly not."

On Sunday, Ecuador's ambassador to the UK left London to return home for talks on Assange's application for asylum. Assange remains under Ecuador's protection while it considers the application, and is "beyond the reach of the police" while he remains in the building.

Earlier this week, a letter signed by leading US figures in support of Assange's application for political asylum in Ecuador was delivered to the country's London embassy. Among its signatories were Michael Moore, Oliver Stone, Noam Chomsky and Danny Glover. Others who put their names to it included the author Naomi Wolf, comedian Bill Maher and Daniel Ellsberg, the former US military analyst turned whistleblower, who leaked the Pentagon Papers in 1971 and has been a long-standing supporter of Assange.
