Wearing a suit and tie, Pete told the media he was looking forward to a rum and coke and seeing his pet cats.
In response to questions about whether he had taken drugs in prison he said:
"Well, I knew it was going to be a bit rough to start with, with the overcrowding and the medical facilities.
"Although they do their best - they are good, they can't really cater for the average junkie."
As he left the prison's grounds Pete said: "Thank you Mrs Thatcher for putting me in the company of the most dangerous criminals in the country".
So what are your thoughts on Pete's early release? Are you surprised, happy, annoyed?
