The Supreme Court has dismissed a bid by WikiLeaks founder Julian Assange to reopen his appeal against extradition to Sweden over alleged sex crimes, BBC News reported.

Seven judges of Britain's top court unanimously dismissed the move by Mr Assange as being "without merit".

Two weeks ago the court rejected his argument that a European arrest warrant for extradition was invalid.

His lawyers had argued that the decision was based on a legal point that had not been argued in court.

Swedish prosecutors want to question Mr Assange over allegations of rape and sexual assault made by two female former Wikileaks volunteers in mid-2010 but have not filed any charges.
