WikiLeaks founder Julian Assange said the Swedish women who have accused him of sexual assault had got into a "tizzy" about the possibility they had caught a sexually transmitted disease from him.

Assange told the BBC that one account of what happened in August - the month at the centre of allegations against him - was that the two women had panicked when they found out they had both slept with him and went to police who "bamboozled" them.

Julian Assange ... life in the shadows.

He insisted he was fighting a Swedish extradition warrant because he believes "no natural justice" would occur in Sweden.

"There are some serious problems with the Swedish prosecution," he said in an interview from the mansion of a wealthy supporter in eastern England where he must stay as part of his bail conditions.
