Up to 200,000 households may be forced to give up their internet connections when the new broadband tax is introduced, it has been claimed.
Continuing his party's campaign against the 50p-a-month landline levy, Shadow Culture Secretary Jeremy Hunt warned of the hidden social costs of the policy.
Speaking after the Treasury confirmed there would be no exemptions to the tax, he said tens of thousands of people will no longer be able to afford the internet.
The tax "isn't fair, isn't necessary and isn't acceptable", Mr Hunt told the Sun.
He also expressed concern about the fact that those people who do not want, or desire the internet, will be forced to pay.
Mr Hunt claimed that up to 3.2 million people in Britain including many pensioners with low-incomes will be charged for a service they have no intention of using.
The Conservative Party has vowed to scrap the broadband tax if it enters power at the coming general election.
