Shorten at the commission: what emerged

SHORTEN IN THE STAND

CREDIBILITY:

* Bill Shorten's credibility as a witness at the royal commission into union corruption called into question.

* Commissioner Dyson Heydon warned Mr Shorten many of his answers are non-responsive.

* Labor spokesman on workplace relations Brendan O'Connor says commissioner Heydon's comments are "remarkable intervention" and "prejudicial".

* Shorten says he understands commissioner Heydon has a job to do, but "it's Tony Abbott's royal commission".

THIESS

* Labor leader Bill Shorten has denied involvement in alleged "bogus" invoices, totalling more than $300,000, sent to construction company Thiess John Holland.

* Some of the money was supposed to be for "research work" on back strain but no evidence has been produced that any research was ever done.

* Deal allegedly linked to enterprise bargaining agreement related to Melbourne's EastLink road project.

CONFLICTS OF INTEREST

* The commission examined a deal between the AWU and glassmaker ACI and $480,000 paid over a two-year period for education and training.

* Deal described in commission as a "serious conflict of interest" as EBA was being negotiated at same time.

* Commission also investigated deal with Chiquita Mushrooms in which company paid $4000 a month for "paid education leave", in deal that allegedly left workers worse off.
