Swedish prosecutors have offered to question WikiLeaks founder Julian Assange in London, potentially breaking a stalemate in an almost five-year investigation into alleged sex crimes.
Prosecutors had previously refused to travel to London, where Assange has spent almost three years inside the Ecuadorean embassy. Lead prosecutor Marianne Ny explained the change in position by saying some of the crimes the 43-year-old Australian is accused of will reach their statute of limitations in August.
"My view has always been that to perform an interview with him at the Ecuadorean embassy in London would lower the quality of the interview, and that he would need to be present in Sweden in any case should there be a trial in the future," Ms Ny said in a statement.
"Now that time is of the essence, I have viewed it therefore necessary to accept such deficiencies in the investigation and likewise take the risk that the interview does not move the case forward," she added.
She said she had made a request to Mr Assange's legal team to interview him in London and to have a DNA sample taken with a swab. She said permission was also being sought from Ecuadorean authorities.
WikiLeaks spokesman Kristinn Hrafnsson said the Swedish decision was "a victory for Julian", but criticised the delay.
"I think it's absolutely outrageous that it took the Swedish prosecutor four and a half years to come to this conclusion after maintaining that she couldn't come to London because it would be illegal to do so," he said. "Obviously that was a bogus argument."
One of Mr Assange's lawyers, Per Samuelson, welcomed the move and said Mr Assange would probably accept the offer.
"This is something we've demanded for over four years," Mr Samuelson said. "Julian Assange wants to be interviewed so he can be exonerated."
The move comes after Mr Assange appealed against his detention order to Sweden's Supreme Court, which earlier this week asked Sweden's prosecutor-general to issue an opinion.
Mr Samuelson said the prosecutor-general had probably ordered Ms Ny to move the case forward by travelling to London.
Mr Assange has not been formally indicted but is wanted for questioning over allegations of sexual misconduct and rape involving two women he met in Sweden in 2010. He denies the allegations.
He has been at the Ecuadorean embassy since June 19 2012.
He has said he has no intention of going to Sweden because he has no guarantees he would not subsequently be sent to the US, where an investigation into WikiLeaks' dissemination of hundreds of thousands of classified documents remains live.
Mr Hrafnsson said the Swedish offer did not mean Mr Assange would be able to walk out of the embassy any time soon.
"We have to worry about the ongoing criminal investigation in the United States," he said.
Ms Ny has dismissed claims of any US involvement in the Swedish investigation.
