Or, more accurately, some additional explaining to do.

The last time Mr Maguire made a public statement was more than two years ago when, via a Facebook video that was quickly deleted, he apologised for breaching Parliament's code of conduct.

That was Mr Maguire's response to being caught up in a Independent Commission Against Corruption (ICAC) inquiry into Canterbury councillors, named Operation Dasha, in July 2018.

ICAC's intercepted phone calls, in which Mr Maguire sought commissions from "mega money" Sydney property deals, resulted in him quitting the Liberals, being forced to resign from Parliament, and helped end his party's near 60-year hold on the Wagga electorate.

Now Mr Maguire is subject to his own ICAC inquiry, which is dedicated to allegations that he used his public office for personal gain between 2012 and 2018.

This new ICAC inquiry into Mr Maguire, named Operation Keppel, has now held three weeks of hearings that included about 50 hours testimony from nearly 30 witnesses.

ICAC has tendered more than 300 exhibits including intercepted phone calls, text messages, emails, invoices and surveillance photos taken in cafes, Chinese restaurants and outside Parliament House.

Mr Maguire will now be called to give evidence on Tuesday, Wednesday and Thursday this week.

The claims heard before ICAC about Mr Maguire's alleged conduct in office have been shocking and extraordinary.

Witnesses have alleged that he used his position and offices in Parliament to chase commissions on property and investment deals, pressure government agencies to suit his friends' business interests, and run a cash-for-visas "scam" across the Riverina.

Whether Mr Maguire will offer denial, explanation or remorse before ICAC will be of great interest to the voters of the Wagga electorate and affect what Parliament's code of conduct refers to as "public confidence in the integrity of government".
