A transgender woman has caused outrage among female prisoners after winning a jail's 'Miss Fitness' competition by a "country mile".

Murderer Alex Stewart – previously Alan Baker – beat other contestants in the multi-discipline fitness tournament at HM Prison Greenock, Scotland, the Daily Record reports.

While living as a man, Stewart killed dad-of-two John Weir, 36, after inviting him to his home.

The two men had met just hours earlier on a gay dating site. He stabbed John at least 16 times.

Stewart has not had gender reassignment surgery but is living life as a woman in the female section of the jail.

The 29-year-old, who has repeatedly complained about her treatment behind bars, triumphed in disciplines including rowing, weights, sit-ups and press-ups.

A source said: “The rest of them shouldn’t have bothered even entering.

“It was surreal. Everybody knew it wasn’t very fair, but nobody was allowed to say it.

“The women inmates have had to accept that Stewart is being allowed to live as a woman, despite not having had surgery.

“That means she is in the showers at the same time as other inmates, which some have found quite awkard.

“She has the right to determine her own gender.

“That is fine because the vast majority of the women believe in inclusiveness and equality.

“She trained hard and won the event by some distance. A country mile.”

“Everybody knew she was training hard for the event,” the source continued. “She did not enter last year and maybe this is a sign of her new confidence.

“She’s actually a nice girl. A bit of a drama queen, but nice.

“But other girls felt ashamed and cheated. They felt that they had no chance right from the start.

“But that didn’t bother Stewart. She just accepted the title and the trophy and seemed very pleased with herself.

“She had trained for a few weeks and as far as she is concerned it all came good.

“None of the prison staff cracked a light that they thought anything was wrong with the competition.

”It didn’t help that the trophy this year was a lot bigger than usual.

“The other contestants just thought they never had a chance, there was a bit of outrage.”

The tournament, held in December, saw about 10 inmates enter. They had to do one minute on several different apparatus to decide who is the fittest.

The source added: “On rowing alone Stewart blew everyone else away. She absolutely smashed it. She did far more strokes in a minute than anyone else.”

As well as the trophy – said to be a foot high – Stewart was rewarded with a “goodie bag” which included chocolate, crisps, snacks, coffee and tea, juice, soap and toiletries.

The source added: “That kind of stuff in jail is real currency.

“You can use it to exchange for anything you want.

“The trophy is inscribed ‘HMP Greenock Miss Fitness 2017’.”

Stewart is said to be learning about hairdressing and how to apply make-up in the prison’s beauty salon.

As Alan Baker, he invited John into his home in Bonhill, near Dumbarton, in January 2013 before killing him.

He claimed to have acted in self defence after his victim was stabbed to death but was convicted of murder and attempting to cover up his crime at the High Court in Dumbarton.

Sentencing Baker at the High Court in Glasgow months later, judge Lord Boyd told Baker he was guilty of a “wicked and brutal” attack. He sentenced him to 19 years.

The court heard how John went to Baker’s home after they swapped details on the dating website.

In his evidence, Baker – who described himself as “predominately gay” – said John seemed “a nice gentleman” and that there was “no animosity”.

The trial heard claims he later pushed John away when the victim allegedly tried to get intimate.

Baker said a fight broke out after he was punched on the chest.

He said when he eventually “came round”, he realised there was a body on the floor and that there was a blade in the bathroom.

Baker then put his victim’s clothes, boots and mobile phone in a bag before dumping them near his flat.

He also tried to clean his blood soaked property before police arrived. Officers found a wheelie bin in the living room.

Baker had said: “I don’t really have a recollection of bringing in the wheelie bin. The only assumption I can make is that I brought it in to dispose of the body in a panic.”

The jury rejected claims he had been acting in self defence.

The murderer previously wrote in prison magazine Inside Time, saying: “To transition in society is hard enough but to do it in prison is even harder.”

A Scottish Prison Service spokeswoman said: “We do not comment on individual inmates.”
