WikiLeaks founder Julian Assange is to find out next week whether his bid to block extradition to Sweden has been successful.
Britain's Supreme Court said on May 23 that the decision on his case will be announced on May 30.
Assange's lawyers have asked the Supreme Court to rule on the validity of the European arrest warrant issued against him.
He is wanted by Swedish prosecutors for questioning on sex crimes allegations relating to accusations made by two Swedish women after he visited that country in 2010.
Swedish prosecutors say the arrest warrant is valid and must be enforced.
Assange insists the sex was consensual and has argued that the attempt to extradite him is politically motivated.
Financial and legal problems have in the last six months slowed the work of his secrets-spilling website WikiLeaks.
