One Nation leader Pauline Hanson has asked her New South Wales senator Brian Burston to resign, after their bitter public feud reached a climax.



The pair have been publicly bickering since Senator Hanson sacked him as the party's whip.

She accused him of "stabbing her in the back" over company tax cuts, and he responded by describing the reaction as a "massive dummy spit".

In the latest development, a letter from the party leader to her NSW senator was brought to his attention during an interview on 2GB radio.

In it, the One Nation leader said she had lost confidence in her offsider, but wished him no animosity.

A copy of the letter shared on the radio station's website says:

"I no longer have confidence in you as an officer of Pauline Hanson's One Nation. You have been removed as deputy registered officer in NSW and in the federal party."

Senator Burston said he had not read the letter and wanted to remain in the party.

"I certainly will not be standing aside for Pauline to put in a crony that's a yes-man or woman to bend to all her requests and suggestions," he told 2GB.

Senator Burston said he believed he was entitled to stay on as a One Nation senator, and that if Senator Hanson disagreed she would have to sack him.

"She's entitled to cancel my membership and that would make me an independent … that's her call," he said.

"I will not be resigning from One Nation and I will certainly never resign my Senate position."

If Senator Burston were to quit, he would be the third One Nation senator to do so in this term of parliament, following Rod Culleton and Fraser Anning.

That would leave Pauline Hanson with only one One Nation colleague — Senator Peter Georgiou.
