Deputy Prime Minister Barnaby Joyce’s new girlfriend was given a job in Resources Minister Matt Canavan’s office in a role which was created specifically for her it has been claimed, after the pair’s relationship was revealed to fellow staff members.

Vikki Campion, who is pregnant with Mr Joyce's child, employed to handle Mr Canavan's social and digital media after her relationship with Mr Joyce created “serious dysfunction” in his office, the Daily Telegraph reports.

Ms Campion was Mr Joyce's press secretary prior to her joining Mr Canavan's office.

Ms Campion, 33, and Mr Joyce, 50, are now living together in the NSW town of Armidale and their baby is due within months.

The newspaper said there was no suggestion Ms Campion was not a suitable candidate for the role. The digital and social media role in Mr Canavan's office has not been filled since she left the position.

Mr Joyce, who last year announced he and his wife Natalie Joyce were separating, broke his silence on the scandal on Wednesday night .

“I’ll say up front that one of the greatest failures in my life was the end of my marriage,” he told ABC’s 7.30 program.

Mrs Joyce released a statement saying she was “deeply saddened” to learn the pair is having a child together.

“I understand that this affair has been going on for many months and started when she (Vikki Campion) was a paid employee,” Ms Joyce said.
