DEMANDS for Julian Assange to be freed from prison are being stepped up amid warnings that the WikiLeaks founder is suffering “severe psychological abuse.”

A group of doctors representing over 250 medical professionals from 35 countries wrote to US President Joe Biden today, urging him to drop charges against Mr Assange under the Espionage Act.

They said: “Mr Assange continues to suffer serious, life-threatening effects of the psychological torture he has been subjected to for more than a decade.”
