Gregor McGill, a senior lawyer at the Crown Prosecution Service, said:
"The CPS has authorised the Metropolitan Police to charge Alan Hagan and to summons a journalist for an offence of conspiracy to commit misconduct in public office.
“We have also decided there is insufficient evidence to charge another individual with conspiracy to commit misconduct in public office.
“Both will appear before Westminster Magistrates’ Court on 10 July 2014.
"May I remind all concerned that criminal proceedings against them will now be commenced and of their right to a fair trial. It is extremely important that there should be no reporting, commentary or sharing of information online which could in any way prejudice these proceedings."
Details of the full charge:
Alan Hagan and a journalist, between 18.1.08 and 29.8.10 conspired together to commit misconduct in public office, contrary to section 1 (1) Criminal Law Act 1977.
