The Conservative Party is offering 100Mbps next-generation broadband for the majority of the country by 2017, if voted in at the next general election.
Speaking on The Andrew Marr Show on Sunday morning, shadow chancellor George Osborne claimed the party could provide new cabling with investment from private companies.
However, any shortfall in funds could be made up with a 3.5 per cent subsidiary from the TV licence fee.
"In the 19th Century we built the railways [and] in the 20th Century we built the motorways," said Osborne.
"In the 21st Century let's build the super-fast broadband network that will create hundreds of thousands of jobs for Britain."
However, Labour has dismissed the plans with Stephen Timms, minister for Digital Britain, saying the Tories are playing "catch up" with plans the Government has already announced, including 2Mbps of broadband for all by 2012.
"Labour have already announced measures for rolling out broadband across the country - and the Tories have opposed the plans to make that happen," he told the BBC.
The Conservatives have been critical of Labour's current plans, claiming they would ditch the broadband tax of 50 pence per month to pay for infrastructure upgrades.
But the Liberal Democrats have agreed with Labour, rubbishing the Conservative's new plans and claiming they don't have the funds available to pay for such a promise.
