Dutton won't produce Robert trip details

Immigration Minister Peter Dutton says it would be wrong for him to provide the airline passenger card details of a ministerial colleague.

Labor used question time on Tuesday to find out whether Stuart Robert's passenger card stated he was on business or a private trip when he made a controversial visit to China in 2014.

Mr Dutton told parliament it would not be appropriate for him to check such details "because of the privacy issues involved".
