A leading English barrister who is carrying out review into PSNI snooping will meet with the policing board in Belfast on Thursday.
Angus McCullough KC is expected to brief members about the high profile review into police surveillance of journalists and others.
The review was set up earlier this year after it emerged that police have been carrying out surveillance on journalists.
In a report to the policing board in June the PSNI admitted making 823 applications for communications data for journalists and lawyers over a 13-year period from 2011-2024.
Weeks later it emerged that more than 4,000 phone communications between 12 journalists were monitored by police over a three-month period.
The review is focused on journalists, lawyers and non-governmental organisations, while the policing bBoard and police ombudsman also fall under its terms of reference.
Details of the spy scandal came to light through the London-based IPT, which is examining allegations that journalists Barry McCaffrey and Trevor Birney, were subjected to unlawful surveillance.
The pair made a complaint to the IPT in 2019 over their arrest the previous year in connection with an acclaimed 2017 documentary about the UVF sectarian murder of six men at the Heights Bar in Loughinisland, Co Down, in June 1994.
A third journalist, RTÉ's Vincent Kearney, who previously worked with the BBC in Belfast, is also known to have been placed under surveillance.
