Julian Assange received permission to marry his partner in prison.
The WikiLeaks founder has been detained in the Category A maximum-security prison in southeast London since 2019 after the United States took legal action to extradite him.
Assange, 50, met his future wife in 2011 while living at the Ecuadorian embassy in the capital.
The couple got engaged in 2017 and have two children, Max, two, and Gabriel, four.
Ms. Moris said: “I am relieved that reason prevailed and I hope there is no further interference with our marriage.”
An Old Bailey judge ruled in January that Assange could not be extradited to the United States, saying it would be “oppressive” to his mental health and that he would be at risk of committing suicide.
He was charged with 17 counts of espionage and one of computer misuse.
If convicted, he could face up to 175 years in prison.
The United States has filed an appeal but the outcome is still pending.
A date for the couple’s wedding has not yet been set.
Ms. Moris revealed how she met Assange while working as a legal investigator and asked to investigate Swedish legal theory and practice.
In a statement supporting a request for bail in April of last year, she wrote: ‘Over time, Julian and I developed a strong intellectual and emotional bond. He became my best friend and I became his.’
The friendship developed and despite ‘extraordinary circumstances’ a close relationship began in 2015, he said.
A spokesman for the Prison Service confirmed that the couple would be allowed to marry.
“Mr. Assange’s request was received, considered, and processed in the usual way by the governor of the prison, as for any other prisoner,” they said.
Britain’s first same-sex prison wedding took place in 2015 when Mikhail Ivan Gallatinov, 40, exchanged vows with Marc Goodwin, 31, at Full Sutton Prison in East Yorkshire, where they were both serving life sentences. for violent attacks against other gay men.
