A Nottingham crime boss who ordered the killings of a couple on the Lincolnshire coast has resorted to moaning about the cost of a stamp from his prison cell.
Colin Gunn played a large part in Nottingham being given the dubious accolade of Britain's gun crime capital.
He was eventually jailed for life in 2006 for conspiracy to murder John and Joan Stirland in their seaside bungalow at Trusthorpe to gain "revenge" on their son.
Gunn, 45, is now urging fellow prisoners at the maximum security Belmarsh Prison, in south east London, to complain that they have been overcharged for sending A4 size mail.
The prison, which holds some of Britain's most dangerous and violent prisoners, including convicted terrorists, has been treating all letters in A4 envelopes as packets and charging prisoners £2.70 for postage, regardless of its weight, he told the prisoners' newspaper Inside Time.
"I would like to inform all prisoners at Belmarsh that they have been overcharged by post room staff when sending out A4 size mail and above, using a cash disbursement form," he wrote.
"A large letter which includes A4 and above has four different weights starting at 0-100gm = 90p and ending at 501-700 gm = £2.30.
"Belmarsh have totally ignored these guidelines and have charged any A4 envelope as a 'packet' with a starting price of £2.70.
"When I raised this I was told I was wrong and an A4 letter is a packet! Unbelievable!
"They now concede I was in fact correct but what is worrying is how long this practice has been going on. Belmarsh were oblivious of their mistake."
A Prison Service spokeswoman said: "No other prisoner at HMP Belmarsh has complained about postage rates."However, the prison is monitoring the situation to ensure that prisoners are paying the correct postage."
