The majority of voters want the carbon tax to be scrapped, a Newspoll has found.

According to the poll published in The Australian, 53 per cent of voters want the Palmer United Party (PUP) to support the repeal bills, while 35 per cent want the party to vote against them.

The latest survey was conducted after the proposal to axe the controversial carbon tax was blocked by PUP senators on Thursday.

According to a Fairfax report, the carbon tax is expected to be repealed within days, after a breakthrough in talks between the government and cross bench senators.

The federal government has since been in talks with PUP staff to discuss further changes to the bills, ahead of it going back to the lower house on Monday.

Prime Minister Tony Abbott has said he is still committed to abolishing the tax.

The Newspoll of 1207 voters taken on Friday, Saturday and Sunday also shows 85 per cent of coalition supporters want the carbon tax scrapped immediately, while eight per cent want it to remain and seven per cent are undecided.

About 30 per cent of Labor supporters also want the tax removed, though the majority, 53 per cent, want Palmer United to block the bills.

But savings aren’t expected from the abolition of the tax, despite Mr Abbott promising on the weekend that households would save $550.

Climate Institute chief executive John Connor told Fairfax that the figure was an “overestimate”.

“Gas prices are climbing sharply for reasons unconnected with the carbon tax, so it’s unlikely there will be any cut in the gas price,” he said.
