Mr Galloway, speaking in a 30 minute video blog on Sunday, said the allegations levelled against Mr Assange could not be considered rape.
He said: "Even taken at its worst, if the allegations made by these two women were true, 100 per cent true, and even if a camera in the room captured them, they don't constitute rape. At least not rape as anyone with any sense can possibly recognise it. And somebody has to say this.
"I mean not everybody needs to be asked prior to each insertion. Some people believe that when you go to bed with somebody, take off your clothes, and have sex with them and then fall asleep, you're already in the sex game with them.
"It might be really bad manners not to have tapped her on the shoulder and said, 'do you mind if I do it again?'. It might be really sordid and bad sexual etiquette, but whatever else it is, it is not rape or you bankrupt the term rape of all meaning."
Mr Galloway was condemned for his comments by women's rights groups, who said he was misrepresenting the law on rape.
Today he issued a statement saying he did not believe the authorities in Britain would have sanctioned a prosecution and that the allegations against Mr Assange had "all the hallmarks of a set-up".
He said: "No never means yes and non-consensual sex is rape. There's no doubt about it and that has always been my position."
But he added: "What occurred is not rape as most people understand it. And it's important to note that the two women involved did not initially claim it."
