The founder of WikiLeaks has appeared in court today in a bid to appeal the decision to extradite him to Sweden to face trial for sexual assault.

Julian Assange was arrested in the UK in December last year. He is currently wanted in Sweden, having been accused of unlawful coercion, sexual molestation and rape. After nine days in Wandsworth Prison, he was granted bail and ordered to return to court in January for a hearing. He planned to fight an extradition order but in February, Judge Howard Riddle, ruled the extradition would not breach Assange's human rights.

He arrived in court today to begin his appeal after branding the extradition order the result of the ''European arrest warrant system run amok''. Assange also claims his arrest is connected to a WikiLeaks campaign in November to publish secret US diplomatic cables and extradition could result in him ensing up facing trial in the US, if Amercia put pressures of Sweden.

It is thought his lawyers will challenge the validity of the arrest as the warrant did not contain full details of the alleged offences as well as claiming extradition in an abuse of his human rights.

If the appeal fails, Assange may head to the Supreme Court of overrule the decision.
