SNP councillors have slammed a "whitewash" reply from the UK Government after elected members requested ministers dropped plans for voter ID.
Westminster intends to require everyone who visits the ballot box in future general elections to produce photo ID before they vote in a bid to tackle fraud.
But Renfrewshire councillors agreed in June to write to Prime Minister Boris Johnson to demand he scrap the plan for fear it would alienate voters in deprived communities who may not have the likes of a passport or driving licence.
Elected members argued voter fraud posed a minor threat, with only 33 allegations of personation - the offence of pretending to be someone else at a polling station - and one conviction recorded at the last general election.
Chloe Smith, minister for the constitution and devolution, replied to the council and said voter fraud was "a crime we cannot allow room for" and the government would be continuing with its plans.
Councillor Kenny MacLaren, who lodged the original motion against the introduction of ID, insisted the move was a Conservative strategy to stop poorer people from casting their ballot.
The Paisley Northwest representative said: "This reply is simply a whitewash and fails to address our concerns regarding the Tory plans to force people to have a photographic ID for future UK elections.
“This is just another attempt by the Tories to attack the poorest in society, by finding a way of limiting their right to vote.
“I’ve been contacted by the Electoral Reform Society who wanted to use Renfrewshire Council as a case study to help promote their campaign to scrap this legislation.
"Anger to this move has been growing steadily. This is clearly a Tory policy to stop the poorest in society from voting.”
At the moment, voters only have to state their name and address at a polling station which the UK Government argues opens up "inexcusable potential" for fraud.
There is no set date for when showing ID will become law but, when it does come into play, acceptable forms will include passports, driving licences, Ministry of Defence identity cards, Proof of Age Standards Scheme (PASS) cards, and Blue Badge photocard parking permits.

Any eligible voter who does not have one of these will be able to apply for a free voter card from their council and the cost of producing these will be covered by the Cabinet Office.
Paisley East and Central councillor Will Mylet added: “Not a single case of voter fraud has been proven to take place in Scotland over the last four years. There is no need for this legislation."
Ms Smith's letter said: "The government in its manifesto committed to protecting the integrity of our democracy by introducing identification to vote.
"Voter fraud is a crime that we cannot allow room for and we must stamp out any potential for it to take place.
"Showing identification to prove who they are is something people of all walks of life already do every day. It is a reasonable and proportionate approach to extend this practice to voting."
