Julian Assange has had a stroke in Belmarsh Prison, his fiancee Stella Moris revealed last night. The WikiLeaks publisher, 50, who is being held on remand in the maximum-security jail while fighting extradition to America, was left with a drooping right eyelid, memory problems and signs of neurological damage. He believes the mini-stroke was triggered by the stress of the ongoing US court action against him, and an overall decline in his health as he faces his third Christmas behind bars.
