Four years after the launch of Operation Elveden, the number of public officials convicted of misconduct in public office stands at 26. A further seven out of the original 80 who were arrested are still awaiting trial, while four have been acquitted.
Their sentences range from between 13 weeks to two years, and total more than 20 years. In contrast, the number of journalists convicted as a result of the operation stands at two.
Former Mirror and News of the World journalist Dan Evans pleaded guilty to conspiracy to commit misconduct in public office. And Sun reporter Anthony France was found guilty of aiding and abetting misconduct in public office after his police source was paid more than £22,000 for stories.
Both were spared jail sentences.
Operation Elveden was launched in the summer of 2011 as a result of disclosures made by News International (now News UK) about payments made by Sun journalists to public officials.
Nearly all of those who have been jailed were prosecuted as a result of information provided by News Corp's Management and Standards Committee to the Met Police.
The vast majority of those convicted were either police or prison officers.
