They "clearly show that I am innocent", Assange said in a statement released on Wednesday, which he described as his full testimony to prosecutors from a recent interview in London.

According to the statement, the woman he is accused of assaulting texted a friend saying Swedish police "made up the charges" against Assange, and that she was "half asleep" on one occasion when Assange had sex with her.

In an extradition hearing in the UK, Swedish prosecutors alleged that the woman, known as SW, was asleep in the same bed as Assange and so was not capable of consent to sexual intercourse.

"This is false," Assange said. "I was certain 'SW' was not asleep. I was also certain she expressly consented to unprotected sex before such intercourse started. This is also evidenced by SW's own text messages."

On Wednesday, Assange released what he described as his "full testimony" from his questioning at the Ecuadorian Embassy in London last month.

It is unclear if it comprises everything he told prosecutors.

According to his legal team, he spent more than seven hours giving a verbal statement to an Ecuadoran prosecutor and Swedish assistant prosecutor Ingrid Isgren.

The next day he spent several hours answering questions from the prosecutors.

The interviews went slowly, his legal team said, because it involved multiple translations into Spanish and Swedish.

The released statement is 19 pages and 10,000 words long. At normal talking speed, it would take about an hour and a half to read aloud.

In the statement, Assange says he travelled to Sweden in August 2010 to negotiate a strategy to protect WikiLeaks' servers.

He met 'SW' in Stockholm when he gave a speech about his work. She sat in the front row and later came to a small private lunch after the talk.

"SW appeared to be sympathetic to my plight and also appeared to be romantically interested in me," Assange said.

They went to see an IMAX film at the National Museum "where she kissed me and placed my hands on her breasts", he said.

She invited him to her home and paid for his train ticket.

Assange claimed he was worried "she might act unpredictably if she believed I was rejecting her" and they had sex "on four or five occasions" – despite the fact he "deeply loved another woman which played on my mind and left me emotionally distracted".

In the morning, he said, they "enjoyed breakfast together (and) I left her home on good terms… she accompanied me to the train station on her bicycle and we kissed each other goodbye".

She later contacted him with concerns about STDs, asking for him to get tested. Two days later she gave a statement to police, and the local news reported that warrants had been issued for Assange's arrest on suspicion of rape and sexual assault.

The statement the woman gave to police has previously been leaked to the media.

In 2010 the Guardian reported the woman claimed she fell asleep again the morning after they had consensual sex, then woke to find Assange having sex with her without a condom.

Assange says Swedish police collected texts from SW's phone which his lawyers have seen.

According to his statement, the texts include:

—  On 17 August, after all sex had occurred, "SW" wrote to a friend that it "turned out all right" other than STD/pregnancy risk

—  On 20 August "SW", while at the police station, wrote that she "did not want to put any charges on Julian Assange" but that "the police were keen on getting their hands on him" ; and that she was "chocked (sic shocked) when they arrested him" because she "only wanted him to take a test".

—  On 21 August "SW" wrote that she "did not want to accuse" Julian Assange "for anything", and that it was the "police who made up the charges (sic)".

Assange also details what he says are unreasonable and unfair delays by Swedish prosecutors, concluding "I have good reason to have concern about whether this 'preliminary investigation' is being conducted in good faith and whether honest and impartial consideration will be given to my statement.

"I suspect that the real purpose of the Swedish prosecutor coming here today is not to obtain my statement but is simply a ruse to tick a box to ensure the technical possibility to indict me, irrespective of how I answer any questions."

In a concluding section of the statement, titled "answer to subsequent questions", Assange says "You have subjected me to six years of unlawful, politicised detention without charge in prison, under house arrest and four and a half years at this embassy. You should have asked me this question six years ago."

It is not clear what question he was asked, but at any rate he responds: "I refer you to my statement where all these questions were answered."

Swedish prosecutors are currently reviewing the results of Assange's interview, and will then decide whether to continue their investigation.
