Former Labor MP turned crossbencher Craig Thomson is due to appear in a Melbourne court today where he will be formally charged with 150 counts of fraud.
Thomson was arrested last week after a long-running investigation by Victoria Police into his alleged misuse of union funds.
He says he is innocent and will contest the charges.
Speaking outside Canberra Airport last night, Thomson admitted the charges have been a distraction for Parliament and his work as the Member for Dobell.
"Obviously I want to make this as quick as we possibly can and answer these charges and get this through as quickly as possible," he said.
"It's obviously a distraction for Parliament, a distraction for my job, and the sooner we can get it done the better.
"To some extent, as bad as being charged can be ... at least it gives the opportunity of resolving this issue."
Thomson said yesterday he had not yet decided whether he would stand for re-election, but .
He said he did not want to pre-empt his defence, but argued the charges were based on a discredited report by Fair Work Australia (FWA).
Accounting giant KPMG were asked to carry out an independent evaluation of FWA's handling of its investigation into Thomson.
Its report made several criticisms of FWA, including that it did not have enough "appropriately qualified and experienced" staff to carry out the investigation.
Thomson said yesterday there was "a whole range of things that are quite unbelievable, but they've happened", adding that "sometimes the truth is stranger than fiction".
