A police officer who supplied a contact with a book of intelligence on rival drug dealers has been jailed for four years, it can now be revealed.
Philip Berry, of Bolton, who worked for Greater Manchester Police (GMP), passed the information to Gary Knox.
Berry, 43, admitted offences including conspiracy to commit misconduct in public office and was jailed in March.
Reporting restrictions were lifted as Knox, 34, of Bolton, was jailed for the same offence in Manchester.
He was sentenced to six years in prison at the city's Minshull Street Crown Court.
Berry was a member of the Bolton drugs squad but was redeployed as a uniformed officer in October 2007.
Police said he started to associate with Knox, of Seathwaite Road, Farnworth, in the summer of 2008.
Berry, of Oldstead Grove, Bolton, gave him a book with drug dealers' names, nicknames and areas of operation in the town. It also included details of police informants.
It was found in the boot of Knox's car in July 2008.
Berry was suspended from the force at the time while allegations he had obtained a fraudulent car loan were investigated.
He had tendered his resignation and his last day with the force was 15 August 2008.
Berry also admitted obtaining money by deception at an earlier hearing.
Simon Byrne, Deputy Chief Constable of Greater Manchester Police, said: "Berry's actions were reprehensible and not only did he let down all his colleagues but also the members of the public he took an oath to protect.
"Berry acted purely out of self-interest and no-one else should be tarnished as a result."
He said the force "took swift action" as soon as his misconduct came to light.
"No one is above the law, and GMP employees who commit crimes will be treated exactly the same way as everyone else," he said.
"The public is right to expect high standards from its police officers and any evidence of criminality or misconduct will be dealt with.
"These are the actions of one man, who in no way reflects the day to day hard work and courage shown by people working for Greater Manchester Police."
