Swedish authorities will appeal against bail granted for WikiLeaks founder Julian Assange at the High Court today .
The 39-year-old whistleblower, who is wanted in Sweden for alleged sex offences, was granted bail at a court hearing on Tuesday after supporters agreed to post a 200,000 cash deposit.
But he was then told he would have to remain behind bars after Swedish authorities said they would fight his release ahead of a full extradition hearing next year.
Assange is expected to appear in the dock for this morning's hearing as he has been granted permission to attend.
The case against him centres on his relations with two women in Stockholm while he was visiting the city in August. The allegations include the rape and molestation of one woman and the molestation and unlawful coercion of another.
