As embattled federal minister Angus Taylor prepares to escape attacks over his character while attending an international conference in Spain, politicians back home are still going toe-to-toe over his past.
Mr Taylor, the minister for energy and emissions reduction, is heading to Madrid for next week's United Nations-led climate talks.
He has faced months of interrogation by Labor over past companies he had been involved in, repeated accusations of misleading parliament and there has been a police investigation into documents he used to attack Sydney Lord Mayor Clover Moore over her travel expenditure.
Labor senator Deborah O'Neill Clare accused Mr Taylor of not meeting ministerial standards but says Prime Minister Scott Morrison continues to look the other way.
She said this week Mr Morrison sacked five department heads and dissolved entire departments.
"But he's still backing a minister who has got an absolute reputation for telling porkies," Senator O'Neill told ABC television on Saturday.
But Liberal senator Amanda Stoker defended Mr Taylor, saying Labor has spent the last two weeks throwing "mud and muck" at a good person in an effort to distract from the fact it doesn't know what it stands for.
"They are at war with themselves over their future direction and they will do anything to avoid having to reveal what they actually stand for," she told ABC television.
