Teachers, civil servants and police are among 264 people that have been charged following an operation targeting those accessing child abuse images online.
A total of 745 suspected paedophiles have been arrested in the National Crime Agency (NCA) investigation, launched just over a year ago.
The agency said 518 children had been protected as a result.
Of those charged, 47 were employed in positions of trust or voluntary roles with access to children, the NCA said.
The government workers include a former UK Border Agency officer, three civil servants, a government employee and someone working in the office of a police and crime commissioner.
Also facing charges are 16 teachers or school staff, a retired magistrate and a police service employee.
They were all investigated under Operation Notarise, the biggest UK inquiry into people sharing child abuse images online since Operation Ore.
