Barnaby Joyce’s affair: How it happened
DEPUTY Prime Minister Barnaby Joyce has denied Vikki Campion was his partner while she was employed in his office.
"I am very aware of the Ministerial Code of Conduct," Mr Joyce told reporters outside Parliament House this morning.
"It is without a shadow of a doubt that Vikki Campion is my partner now. But when she worked in my office, she was not my partner.
"When she worked in Matt Canavan's office, she was not my partner. And Damian Drum was not a minister."
But it's understood Ms Campion was employed in the Deputy Prime Minister's office for a number of weeks in later July and early August last year, after she left Resource Minister Matt Canavan's office.
