Tribunal investigating lawfulness of 2013 PSNI actions after complaint by Trevor Birney and Barry McCaffrey

A secretive tribunal is looking into allegations that UK authorities spied on investigative journalists in Northern Ireland to identify their sources.

The investigatory powers tribunal (IPT) is examining a complaint by two journalists who asked the body to find out whether police in Northern Ireland and Durham, as well as MI5 and GCHQ, used intrusive surveillance powers against them.
