London: The embassy in London where Julian Assange has lived for more than three years considered getting rid of their long-term guest by helping him flee in fancy dress, it emerged on Tuesday.

Leaked documents showed Ecuadorian diplomats were becoming increasingly concerned about the Australian's behaviour and drew up a number of bizarre plans to allow him to leave the building without being arrested by waiting police officers.

Mr Assange, founder of the WikiLeaks website, claimed asylum in the Ecuadorian embassy in June 2012 to avoid being extradited to Sweden to face questioning over rape and sexual assault allegations. He has not left the building since.

One option set out by diplomatic staff was to help Mr Assange make a rooftop flit to a nearby helipad.
