Former Australian Prime Minister Scott Morrison has resisted calls to resign from parliament, after news emerged that he had secretly assumed five additional roles during his tenure.

He defended his decision - which was taken during the pandemic - as "necessary" in "extraordinary times".

Mr Morrison is currently the member of parliament for Cook in New South Wales.

The revelations caused uproar among the public and his colleagues, with one calling his behaviour "dictatorial".

Mr Morrison became joint minister for the health portfolio from March 2020, and for finance, treasury, home affairs and resources from May 2021.

In a news conference on Wednesday, he defended his decision by saying he was "acting in the national interest in a crisis" in case a minister was incapacitated with Covid-19.

"They were put in there as a safeguard as a 'break-glass-in-case-of-emergency' and as a result, thankfully, we didn't need to break the glass," he said.

Mr Morrison added that he had never acted as minister despite being secretly sworn into those portfolios.

"I did not instruct any department that I was to have jurisdiction for carriage of any of the issues that the ministers were dealing with on a day-to-day basis," he said.

When queried about why he had not disclosed the expansion of portfolios to cabinet or to the broader public, he argued there was a risk the powers he took on could have been misconstrued.
