Labour leader David Shearer has refused to comment on reports that his press secretary's partner was the source for apparent leaks to Labour about Prime Minister John Key's visit to the Government Communications Security Bureau in February.
Labour has claimed that several well-placed sources have told them that the Prime Minister had mentioned Kim Dotcom when he was addressing staff in the GCSB cafeteria and that the visit was recorded.
However, the GCSB has stated that it had no such recording of the visit. It had also started an investigation into who was leaking information.
Newstalk Zb reported this morning that the leak was through Mr Shearer's press secretary Fran Mold's partner, who used to work for the GCSB.
Mr Shearer refused to comment on that this morning, saying journalists did not divulge their sources and neither would he.
