A spokesman for Senator Cash said she absolutely did not condone and crimina behaviour.

“We’re going to get it cleaned up as soon as possible and get on with the job,” he said.

Senator Cash, who has faced some criticism over her performance, voted for Scott Morrison in the leadership spill on Friday after being one of the three ministers to announce they had lost confidence in the Turnbull government on Thursday.

Ms Cash has now been given the Small Business, Skills and Vocational Education portfolio, elevated to cabinet following sustained calls from the conservative faction to give it increased prominence in a bid to sharpen its anti-business attacks on Labor in the lead-up to the next election.
