Scott Morrison needs to stop politicising the Australian Treasury because it risks undermining the confidence and credibility of the work it produces, much of which Australian markets, businesses and consumers rely upon.

It says a lot about the quality of Scott Morrison as Treasurer that he is incapable of making an argument without politicising the Treasury and as he gets more desperate, the intensity of the politicisation is increasing.

The most recent and egregious example of this politicisation was on 30 November when the Treasurer released Treasury costings of Labor tax policies based on assumptions hed given to Treasury.

Today we see this approach again with selective quotes from a Treasury submission given toThe Australiannewspaper.

On most occasions, just like today, Mr Morrison refuses to release whatever he has commissioned from Treasury for public scrutiny.

Its usually weeks or months later that the work gets released following LaborFreedom of Informationrequests, which is exactly what happened a few weeks ago when the Treasury published a report late on a Friday afternoon a report the Treasurer had quoted from previously but refused to publicly release.

These are some of the low lights of Scott Morrisons politicisation of the Treasury:

• 30 November 2017 Morrison gives Treasury costings of Labor tax policies to media.
• 20 November 2017 Morrison gets taxpayer-funded Treasury glossy sent to ASX200 CEOs with a letter alleging Labor had a dark vision for the Australian economy.
• 8 November 2017 Morrison gives Treasury report on US corporate tax reform toThe Australian
• 29 September 2017 Morrison quotes from Treasury report he commissioned but is only released after Labor FOI.
• 9 December 2016 A Treasury commissioned independent review of Labors GFC economic policies from an academic previously criticised by former Treasury Secretary Martin Parkinson finds its way toThe Australian.

Mr Morrison, stop politicising Treasury.
