UPDATE 1-Assange ask Swedish court to overturn arrest warrant

STOCKHOLM Feb 22 (Reuters) - Lawyers for Julian Assange have asked a Swedish court to overturn an arrest warrant for the Wikileaks founder following a ruling by a U.N. panel that his stay in Ecuador's London embassy amounts to arbitrary detention.
Assange, 44, took refuge at the embassy in June 2012 to avoid extradition to Sweden, where he is wanted for questioning over allegations, which he denies, that he committed rape in 2010.
He says the accusation is a ploy that would eventually lead to his extradition to the United States, where a criminal investigation into the activities of WikiLeaks is still open.
"We consider that there have arisen a number of new circumstances which mean there is reason to review the earlier decision," Thomas Olsson, one of Assange's lawyers, said on Monday.
A second lawyer representing Assange said he remained willing to be questioned in the Ecuadoran embassy, according to Sweden's national news agency.
Ecuador has granted Assange asylum and he says his rights have been infringed because he is unable to travel to the South American country.
Both Britain and Sweden denied that Assange was being deprived of freedom and the Swedish prosecutor in charge of the case has said she will renew an application to interview Assange.
Prosecutor Marianne Ny said the U.N. panels' non-binding ruling had no impact on the case. Continuación...
