Stockholm: Lawyers for WikiLeaks founder Julian Assange have filed an appeal to Sweden's Supreme Court seeking to quash the 2010 warrant for his arrest on accusations of rape and molestation.

Mr Assange's lawyer Per Samuelsson said he lodged the appeal with Sweden's top court on Wednesday afternoon to end the stand-off.

The Australian remains holed up in Ecuador's embassy in London to avoid arrest and extradition, while Swedish prosecutors refuse requests he be questioned there.

"We have to end this - the situation is completely stalled, and that's the point we raised in our appeal," Mr Samuelsson said in criticising what he called the "total passivity" of prosecutors who he said "have done nothing in four years".
