Marc Goodwin, 31 and Mikhail Gallatinov, 40, will tie the knot in what is thought to be the UK’s first jail same-sex wedding next month.
The wedding ceremony will take place at top-security Full Sutton prison, near York, where both men are serving life sentences.
Goodwin was jailed for life in 2007 for the homophobic murder of 57-year-old Malcolm Benfold in Blackpool. He was sentenced to a minimum of 18 years before he is considered for parole.
Goodwin led a three member gang who sought out gay men in Blackpool for “gay bashing” (his own words at the time).
At the time, a judge at Preston Crown Court heard that Goodwin, of Airdrie, Lanarkshire, Scotland, denied the homophobic murder motive and said committed the crime in order to get cash for alcohol.
Benfold was killed with series of fatal blows from either feet or fists, the court heard, which police described as “a savage, senseless homophobic attack that resulted in the death of a harmless man”.
Wendy Bridge, Benfold’s sister, who visited Goodwin told the UK daily The Mirror: “He said he was really sorry and wished there was still the death penalty as he would be dead too.”
Gallatinov was convicted of murdering his lover, Adrian Kaminsky, 28, in Manchester in 1997 and sentenced to life with a minimum of 20 years in prison.
At the time, Manchester Crown Court heard that he also was convicted for sexual offences against children, and was under surveillance by undercover police when he strangled Mr Kaminsky.
Trial judge Judge Rhys Davies QC said: “This was a cold-blooded, well-planned, callous, chilling and apparently motiveless killing.”
A Ministry of Justice spokeswoman refused to comment on the country’s first jail gay wedding, stating: “We do not comment on individuals.
“Prisoners are entitled to apply to be married in prison under the Marriages Act 1983.
“This would take place at no cost to the taxpayer and there is no possibility that they would share a cell.”
