Thomson documents released

The Senate has released previously unpublished documents about disgraced former Labor MP Craig Thomson, now awaiting sentence after being convicted of fraud.

They were provided to the parliamentary workplace relations committee by Fair Work Australia from its investigation into the Health Services Union.

Liberal senator Concetta Fierravanti-Wells said on Tuesday the documents had been suppressed until now by the former Labor government.

She said the Fair Work Australia report on Thomson's role in the HSU was published but the annexures were withheld and only available for inspection by senators behind closed doors.

"A light will finally be shone on documents that record some of the darkest activities of the Labor Party, their members and the union bosses that support them," she said in a statement.

Thomson, who entered parliament in 2008, was convicted by the Melbourne Magistrates Court late last month.

He's facing sentence on multiple counts of theft and fraud including those relating to the use of a union credit card to pay for prostitutes.
