PSNI chief constables due at Leveson Inquiry
The chief constable of the PSNI and his immediate predecessor are due to give evidence to the inquiry into media ethics on Wednesday.
Matt Baggott and Sir Hugh Orde will appear at the Leveson Inquiry at the High Court in London later.
The inquiry was set up by Prime Minister David Cameron in November 2011 after revelations of phone hacking by journalists at the News of the World.
It is now focusing on the relationship between police and the press.
DUP MP Ian Paisley jnr has previously called for the inquiry to look at Northern Ireland, claiming that his phone was hacked while he was a Stormont minister.
Earlier this month, the chief of the Metropolitan Police told the inquiry that relations between the police and the press were too close in the past.
Commissioner Bernard Hogan-Howe said that when he took over at the force in 2011, he picked up concerns about an overly "close social relationship".
