One Nation leader Pauline Hanson has told Liberal National Party (LNP) MP George Christensen to stay loyal to his party or risk destabilising the Government.

Says Australians want leadership like that displayed by Vladimir Putin Voices "in-principle" support for the cut to Sunday penalty rates

The comments came in a wide-ranging interview on Insiders that also covered cuts to penalty rates, vaccinations and Russian President Vladimir Putin's "patriotic leadership".

Mr Christensen resigned as the Nationals chief whip last week, saying he could not be both a rebel and an enforcer of party discipline.

Last month, the maverick MP threatened to quit the LNP unless the Government intervened in a dispute between sugar mills and cane growers in his electorate.

He penned a "letter of demand" about the sugar industry stoush to Prime Minister Malcolm Turnbull, in which he contemplated resigning but never sent it.

Senator Hanson told Insiders host Barrie Cassidy this morning she had not encouraged Mr Christensen to leave the party.

"I advise him, stay where you are because if he jumps ship it is going to destabilise the Government and I don't believe the people want that and they would not want that from me," she said.

"Stabilise the Government, because we need that."

Senator Hanson compared Mr Christensen's circumstances to former senator Rod Culleton, who quit One Nation to sit as an independent in the Senate, before he was disqualified.

"If you are elected to Parliament with a party, that's what the people voted you in and you should stay with the party," she said.

"If he actually says: 'No, I've had enough and I can't stay with the National Party and they are not representing my party and what I want', then of course, if he wants to come across to One Nation I'm not going to say no."

Hanson gives 'in-principle' support for penalty rate cuts

Senator Hanson also weighed in on the fierce political battle over penalty rates, giving "in-principle support" for the Fair Work Commission's decision to reduce Sunday rates in some industries.

The Commission has ruled Sunday penalty rates will be reduced for some workers in retail, hospitality and fast food industries.

Senator Hanson told Insiders cutting penalty rates would allow businesses to open on weekends and employ more people.

"I had my own business, now if you go into a fish and chip shop, I'd have to pay $34 an hour to employ someone, yet McDonald's down the road can only pay $26 an hour," she said.

"This is the EBA … this is what the unions have negotiated."

Senator Hanson said she had not decided whether or not to support the Government's proposed cuts to the corporate tax rate, saying she would rather the Commonwealth pressure the states to lower the payroll tax.

The Federal Government has been calling for the company tax rate to be lowered from 30 per cent to 25 per cent, arguing it would make Australian businesses more competitive.

Senator Hanson said she had discussed the issue of payroll tax with the Treasurer.

"It's a stupid tax," she said.

"The more people you can employ, the more you get hit with taxes, it's stifling growth, it's stifling employment."

Vaccination-linked welfare program like 'dictatorship'

Sorry, this video has expired Barrie Cassidy questioned Senator Hanson on her comments linking vaccinations to autism.

Senator Hanson also accused the Government of "blackmailing" parents by linking welfare payments to vaccination programs.

Successive governments have sought to boost immunisation rates by cutting childcare subsidies and family tax benefits to parents who refuse to vaccinate their children.

But the One Nation leader said parents should be allowed to have their children tested before vaccinations, saying some had reported problems.

"What I don't like about it is the blackmailing that's happening with the Government," she said.

"Don't do that to people, that's a dictatorship."

Putin and missing flight MH17

Senator Hanson said Australians wanted to see leadership similar to that displayed by Russian President Vladimir Putin.

"He is very patriotic towards his country, the people love him, he is doing so well for the country," she said.

"So many Australians here want that leadership here in Australia."

"I think he is a strong man and I think about 97 per cent of people in his country respect him as a leader for their nation," she added, citing a non-specific Russian opinion poll.

Labor's Brendan O'Connor said most Australians would find her comments unacceptable and offensive.

"I find it quite offensive and contemptible that Senator Hanson would applaud and laud such a leader given the complicity of Putin in the deaths of 38 Australians," he said.

In the interview, Senator Hanson asked for proof that Russia was involved in the downing of Malaysian Airlines flight MH17, which killed 38 Australians.
