"We should have the broader discussion about what is it that you'd be most interested in doing, then decide what shape that could take that would fulfil that, is what I'm getting at, whether it's a full-time or part-time job at a (constituency) office, whether it is appointments to boards or commissions, whether it is also going on the (party executive),'' Sorbara is heard saying in the recording.

Wynne has said Olivier's allegations are false, insisting that "there were no specific offers made in requests for any specific action" to Olivier.

The Liberals have said Olivier's recordings vindicate them, as they were discussing ways Olivier could remain involved in the party or with accessibility work, but only after he was already told he wouldn't be the candidate.

They also said Lougheed is neither a government nor Liberal staff member and speaks for himself.

In a statement to local media in December, Lougheed said that he does not have the authority to offer jobs and "at no time'' did he promise Olivier a job or appointment if he stepped aside.

The opposition parties had asked the OPP to investigate Olivier's allegations, suggesting they could contravene sections of the Criminal Code that relate to offering government advantages and securing appointments.

The OPP determined last month that no criminal offence was committed, but later reopen the investigation in light of Olivier's audio.

A spokeswoman for Wynne said late Thursday that it is common for an investigator to make an assertion in order to obtain a warrant.

"It is in no way confirmation that an offense has occurred," the spokeswoman said in an email.

Elections Ontario is also investigating and has interviewed both Wynne and Sorbara, after the New Democrats suggested the Liberals' alleged conduct violates the Election Act.
