Nothing more to say on Ashby: Brough

Special Minister of State Mal Brough says he's made a full explanation in relation to claims about former Speaker Peter Slipper's diary.

Australian Federal Police investigators last week visited Mr Brough at his Queensland home.

The search, for which the AFP had a warrant, was in connection with allegations Mr Slipper's diary was illegally copied in 2012.

Shadow attorney-general Mark Dreyfus has asked Mr Brough in question time whether it was appropriate for someone to "procure another person to access restricted data held on a government computer".

Mr Brough, whose portfolio puts him in charge of parliamentary integrity, said the opposition was "playing games".

"I have made a full statement and none of what I have said has ever been repudiated, nothing has ever been added to," Mr Brough told parliament on Monday.

"I think it would do us all well to ensure that any issues that are being dealt with by the authorities are done so."

Police also searched the home of Mr Slipper's former staffer James Ashby last week.

Prime Minister Malcolm Turnbull told parliament the minister had his confidence.
