Labor demands Joyce flight details

Labor is demanding to see the details of taxpayer-funded flights Barnaby Joyce and his staffer-turned-partner Vikki Campion took in 2017.

The deputy prime minister's relationship with his now-pregnant partner raised concerns about the potential misuse of taxpayer funds while she worked in various ministerial and MP offices.

Labor senator Kimberley Kitching on Wednesday tabled a notice of motion calling for the details of Mr Joyce and Ms Campion's "special purpose travel" and any international flights.

Mr Joyce has denied breaching the ministerial code of conduct, which says frontbenchers cannot employ "close" relatives or partners or get them work in other ministerial offices "without the prime minister's express approval".

He says Ms Campion was not his partner when she worked in his and Matt Canavan's office, while Damian Drum was not a minister when she transferred to his office.
