Magic Talk host Sean Plunket told the Opposition leader the "issue remains" that the National Party received money that may have been illegally mishandled before it reached the party's accounts.

Bridges responded: "It's safe to say that we don't have the intention of keeping the donation, in fact, we've been in communication and written to the Electoral Commission about that, for them to help us and give us advice on what to do with that donation."

The SFO launched an investigation in March 2019 into National Party donations after the police referred a complaint by former National MP Jami-Lee Ross who accused Bridges of fraud.

Ross said in October 2018 Bridges broke the law, alleging the Opposition leader had asked him to collect a $100,000 donation from wealthy Chinese businessman Zhang Yikun and not disclose it properly.

Ross said the donation arrived in eight amounts smaller than $15,000 - the threshold at which donations have to be declared by law - and that Bridges had stressed it should not be made public.

Ross released a recorded phone conversation between him and Bridges at the time, where he could be heard asking his then-leader what to do with the $100,000 donation.

Bridges told Magic Talk he had nothing to do with the donation except attend a fundraising dinner in May 2018 with Zhang Yikun, whom Bridges was photographed with.
