MSPs have been urged to support calls for the abolition of the council tax.
Scottish Socialist Party MSPs, like the Scottish National Party and the Liberal Democrats, want the charge replaced with an income-based alternative.
SSP leader Tommy Sheridan claimed that the most recent opinion poll showed 77% of Scots were in favour of abolishing the charge.
Mr Sheridan led a debate on the tax at Holyrood on Thursday and said MSPs should reflect public opinion.
He urged all parties opposed to the charge to vote with the Socialists.
