Labor accuses Malcolm Turnbull of putting politics ahead of cyber security

Prime minister says Labor, Nick Xenophon and Greens were all invited to a briefing, but they have no record of this and only found out through the media

Labor has accused Malcolm Turnbull of putting his own political purposes ahead of national security by publicising plans for a secret briefing for political parties to head off "Russian-style" cyber attacks.

The prime minister had told the Australian newspaper about his plans to invite opposition parties to secret classified briefings - but did not inform them except through the media.
