Businessman Nathan Tinkler and former Labor ministers to front corruption watchdog

Businessman Nathan Tinkler is scheduled to front a corruption inquiry for a grilling about his company's role in illegal campaign donations.

The Independent Commission Against Corruption (ICAC) has heard allegations Mr Tinkler's company Buildev funnelled money into the campaign accounts of several NSW Liberal MPs before the 2011 election.

The ICAC has also heard Buildev put money into a campaign to dethrone Newcastle Labor MP Jodi McKay in 2011 because she opposed plans to build a coal-loading facility on the Newcastle foreshore.

Property developers have been banned from making political donations in NSW since 2009.

Mr Tinkler, who appeared at the corruption watchdog in May, is scheduled to front the corruption watchdog today.

Former Labor ministers Tony Kelly and Joe Tripodi, who have both been found corrupt in the past by the ICAC, are also listed to give evidence.
