Julian Assange has received a visit from film-maker Michael Moore where he is holed up in the Ecuadorian embassy in London.

Oscar-winning documentary film-maker Michael Moore has taken time out from promoting his new film to meet WikiLeaks founder Julian Assange.

The American has been a supporter of the Australian for years but they had never met in person.

Moore paid a visit to the Ecuadorian embassy in London, where Assange is living as he seeks to avoid extradition to Sweden, where he is wanted for questioning over a sex allegation, which he has always denied.

He believes that if he travels to Sweden he will be taken to the United States to be quizzed about the activities of WikiLeaks.

Assange will have been inside the embassy for four years on June 19.

A number of cities around the world, including Paris, Berlin and New York, will hold special events to mark the anniversary.

Patti Smith and PJ Harvey will play live at two venues.

In Moore's new film, Where To Invade Next, he examines how Europeans view work, education, healthcare, sex, equality and other issues.
