Andrei Molodkin threatened to destroy works by Picasso and others if the activist died in prison. Now, he is exhibiting a portrait of Assange in a new show

Andrei Molodkin had threatened to destroy unidentified works by artists including Pablo Picasso if the WikiLeaks founder died in jail, but now they are to be set free

Hand-painted portraits of the WikiLeaks founder and his wife Stella were smuggled into a display case at the London museum in April

The Russian artist Andrei Molodkin says he will destroy works by Jake Chapman, Sarah Lucas, Picasso and Rembrandt if the Wikileaks founder dies in jail

The work invites audience participation and is about defending "freedom of speech", says its creator Davide Dormino

Physical copies of some of the top secret US diplomatic cables leaked by Assange will be on show
