Lawyers working on behalf of Julian Assange have revealed they will appeal to US President-elect Donald Trump to end a criminal investigation into the WikiLeaks founder.

Mr Assange was quizzed on Monday and Tuesday by Swedish prosecutors inside the Ecuadorian Embassy over sex allegations which he has denied.

The WikiLeaks founder is also subject to a criminal probe in the US over the publication of classified documents about the wars in Iraq and Afghanistan provided by whistleblower Bradley Manning.

Mr Assange claimed political asylum inside the London embassy, where he has been holed up since 2012, amid fears he could be extradited to the US to face charges.

Following his interview with Swedish prosecutors, his lawyer Jennifer Robinson said he had co-operated fully and hoped the matter can now be closed.

She said: "It is important to remember that he has never been charged and has already been cleared once by the previous prosecutor.

"We hope and expect that the prosecutor will come to the same conclusion."

She added that she hoped to strike a dialogue with Mr Trump over the ongoing investigation with the US which was launched in 2010.

She said: “During that time we have repeatedly called for the investigation to be closed on the grounds it violates the First Amendment , and places a chill on freedom of speech and reporting.

"Through US counsel, we had reached out to the Obama administration, most recently just a few months ago, and we will continue to do so with future US administrations until the investigation is closed."

Ms Robinson added the "absurd politicised situation" must draw to a close.

Sweden's assistant prosecutor Ingrid Isgren and police inspector Cecilia Redell were present while questions were put to Mr Assange.

They made no comment as they returned to Sweden, but a statement said: "As the investigation is ongoing, it is subject to confidentiality.

This confidentiality also applies according to Ecuadorian legislation for the investigative measures conducted at the embassy.

“Therefore, the prosecutors cannot provide information concerning details of the investigation."
