Two convicted murderers serving life sentences are to be wed behind bars, in what will be the first prison same-sex wedding in the UK.

It has been reported that Mikhail Gallatinov (40) and Marc Goodwin (31) have received special permission to get married while in prison. The wedding will reportedly take place next month at the maximum-security Full Sutton Prison, near York, and is thought to be the first of it’s kind in the United Kingdom. Same-sex marriage has been legal in the UK since March 2014.

In 2007, Goodwin was convicted of attacking a 53 year-old gay man in Blackpool. The incident was thought to be a random homophobic attack. At the time, the judge heard that Goodwin has previously talked about committing “gay bashings”.

In 1997, Mikhail Gallatinov was given a life sentence after he strangled his male partner, Adrian Kaminsky, to death in what the judge called a “callous, cold-blooded killing” with no motive. At the time of the murder, Gallatinov was under surveillance by undercover police for sexual offences against children. Manchester Crown Court heard that he was a predatory paedophile.

The ceremony will take place at top-security Full Sutton prison, near York, where both men are serving life sentences.
