Spying leak report due

Prime Minister John Key will this afternoon release the findings of an investigation into the leak of the report into the Government Communications Security Bureau (GCSB).

The report, seen in April by Fairfax Media, revealed more than 80 people may have been illegally spied on by the GCSB.

Former top public servant David Henry was called in to investigate who leaked the report.

Key's office says Henry's report will be released at a press conference at 3.30pm today.
