The infamous prisoner Charles Bronson has said he's angry because delays to his bid for freedom mean he can't enjoy Christmas dinner with his mother.
This year, the 69-year-old became the first person ever in Britain to be given a public parole hearing, after spending the majority of his life behind bars.
But after at first hoping it would take place in the summer, it was pushed back until December - and now looks unlikely to happen until 2023.
In a handwritten letter to WalesOnline from his cell in the high-security HMP Woodhill in Milton Keynes, Bronson – whose mum Eira comes from Aberystwyth – he described the set back as a "disgrace."
He also said of his now-ruined plans for a festive family reunion: "Jingle f*****g b*****ks!"
He wrote: "I always say: 'Never plan anything in prison unless it's an escape.' Because you're just not in control of your own life. This Xmas I was looking forward to dinner with my mother.
"I believed I had a good chance of squeezing out some jam roll (parole) on December 12 - but now that won't happen 'til 2023.
"That's how this system 'works' – they couldn't run a p**s-up in a brewery. That's why there are so many suicides inside and why the women left on the outside lose hope."
Bronson was originally given a seven-year sentence for an armed raid on a Cheshire post office in 1974 from which he netted just £26.18.
But that initial sentence has increased several times over the decades as a result of various violent incidents which saw him assault other inmates and take members of prison staff hostage.
Nevertheless since changing his surname to Salvador in 2014 – in tribute to the surrealist painter Dali–- he's become a prolific artist, devoting himself to raising money for various charities, writing books, and trying to encourage kids to stay away from crime.
"I've given these hypocrites years of good behaviour and they've given me nothing back. It's a disgrace and I'm sick of it," said Bronson. "'Jingle f*****g b*****s', I say. But it is Xmas after all, so one must not be angry."
He added: "Will I make it out for Christmas next year, who knows? But there's one sure thing – I'll get out of here one day and it won't be in a body bag."
