The Scottish Greens have accused the SNP of putting "pride" ahead of their plans to reform council tax.

MSPs will vote on a motion to increase council tax for more expensive homes on Thursday evening.

The Greens have submitted an amendment to the proposal saying the plans "undermine" local autonomy.

All opposition MSPs are expected to back the amendment.

The SNP have submitted an amendment to the Greens' motion which removes the criticism of the Scottish Government.

First Minister Nicola Sturgeon said she is confident in the proposals but is committed to talking to other parties about the changes, which aim to raise an extra £100m for education in Scotland.

Speaking at First Minister's Questions ahead of the vote on Thursday, Green co-convener Patrick Harvie said: "The media is reporting that the SNP may not even back its own policy proposal at the end of the day.

"A minority Government must sometimes accept modest criticisms. We have been clear at every step that we are expressing our criticisms without putting the reforms in any danger.

"Does the First Minister remain committed to her party's proposal to change council tax bands? Will she be voting for it, as we will, tonight?"

Harvie continued: "The Green amendment deletes nothing from the government's proposals, it changes nothing in what will happen if the bands are changed and the revenue is raised.

"It only has modest criticisms which are widely shared."

He added: "Is wounded pride really worth £100m?

"The only way in which the SNP proposal can fall is if the SNP let it fall."

The First Minister responded, saying the SNP amendment highlighted the need for progressiveness and fairness in local government taxation.

She said: "There's an opportunity for a progressive alliance behind the government's amendment tonight, that talks about genuine local democracy and fairness in taxation.

"We are absolutely confident in the proposals we're putting forward but we are also signalling a willingness to talk to other parties across the chamber to further the discussion about progressive taxation.

"I hope that we can get to that position tonight, and I hope that we will vote for sensible changes that deliver £100 million for our schools."

The proposals would lead to a council tax increase for properties in the four highest bands, E to H.

An average band E household would pay about £2 per week more and the average household in band H about £10 a week more.

The cash raised would be used to close the attainment gap in Scotland's schools.
