Mining magnate Clive Palmer has voluntarily deregistered the United Australia Party in a surprise move that leaves his only senator without a registered party.
A notice published by the Australian Electoral Commission confirmed the UAP had been deregistered on 8 September.
Despite the move, election and opinion poll expert Kevin Bonham said it may be possible for UAP's only elected member, Victorian senator Ralph Babet, to continue to sit in parliament as a representative of the UAP.
"As I understand it, what the Senate recognises as a party and what the party registration system recognises as a party are two separate things," he told SBS News.
"So if the Senate choses to keep calling him a United Australia Party senator, then they can."

In 2017, the former Palmer United Party was deregistered and then re-emerged as the United Australia Party in 2000.
But Mr Bonham said the Palmer United Party did not have any members of parliament at that stage and so the previous situation was a bit different.
Deregistering the party also means the name United Australia Party will not be able to be used again at the next election.
"There's a section of the Electoral Act that says when a party voluntarily deregisters you can't register the same party name, or a name that is very similar to the same party name before the next election has passed," Mr Bonham said.

“I don’t know what the technicalities are. But trademark-wise, I will still be calling myself a member of the United Australia Party,” he said.
He said the party had not spilt despite the party being deregistered.
Senator Babet has been described as Mr Palmer's "$100 million man" for being the sole beneficiary of the businessman's federal election campaign this year.
The party was registered in December 2018 and ran candidates at the federal election the following year.
However, the party failed to get a member elected in either house of parliament at the 2019 election despite the multi-million dollar ad spend, before securing one spot the last time around.
SBS News has contacted Senator Babet's office for comment.
