Swedish prosecutors will make their appeal against bail for Wikileaks founder Julian Assange at the High Court on Thursday.
The 39-year-old was granted bail at City of Westminster Magistrates' Court on Tuesday on the condition he provides sureties of £240,000 in cash.
But he was forced to remain in Wandsworth Prison pending the appeal.
Mr Assange is fighting extradition to Sweden, where he denies sexually assaulting two women.
He argues that the allegations against him are politically motivated and are designed to distract attention from the sensitive material being exposed by his whistle-blowing website.
