Julian Assange’s mother has railed against Theresa May, Ecuador’s president and the judge who branded the WikiLeaks founder a “narcissist” in a stream of tweets demanding her son is released.

Pledging to “fight like hell”, Christine Assange said the Prime Minister was “trying to divert attention away from her Brexit dog’s breakfast by cheering on the thuggish, brutal, unlawful arrest of my courageous, tortured multi-award winning journalist son Julian!”

Mrs Assange, who lives in Australia, tweeted and shared articles regularly after her son was seen being forcibly removed from the Ecuadorean embassy on Thursday.

Addressing the country’s president, Lenin Moreno, she tweeted: “Shame on you @Lenin #Moreno! May the Ecuadorean people seek vengeance upon you, you dirty, deceitful, rotten traitor!

“May the face of my suffering son haunt your sleepless nights.. And may your soul writhe forever in torturous Purgatory as you have tortured my beloved son!””

Assange was taken to Westminster Magistrates’ Court after his removal from the embassy on Thursday.

District Judge Michael Snow described his behaviour as “that of a narcissist who cannot get beyond his own selfish interests”.

His mother tweeted: “UK judge should NOT be making statements like this! This is (a) rubbish Legal process!”

On Friday morning UK time, she issued a plea to police, prison officers and court staff.

She said her son had been “detained without charge”, “deprived of fresh air, exercise and sun” and “denied proper medical/dental care” for several years.

She also claimed he had been “isolated/tortured” for a year.

“Please be patient, gentle & kind to him,” she tweeted.
