Jeremy Corbyn has called for every home and business in Britain to have guaranteed access to high-speed broadband.
Speaking at the launch of a seven-point digital democracy manifesto, the Labour Leader said universal high-speed broadband access is essential for supporting remote communities throughout the UK.
He argued that ensuring access to good-quality connections at affordable prices is also important as it can enable businesses to trade and diversify.
Furthermore, Mr Corbyn said slow broadband is a "source of social and economic exclusion" and a "barrier to learning".
He has therefore committed to placing a guarantee of access to high-speed broadband in a digital bill of rights, should Labour win the next general election.
Mr Corbyn stated that providing a genuinely universal service across the country would cost around £25 billion, with this sum underwritten by a newly established National Investment Bank and backed up by a legally binding universal obligation for a minimum connectivity speed.
"The investment of £25 billion seems to me to be money extremely well spent that will help to reduce the levels of regional imbalance and regional inequality in Britain," he said.
"In some parts of the country, people have laid their own broadband cable because farmers were fed up with being unable to quickly access the internet to get a reasonable price or sell their products.
"This is about ensuring everyone has access to the equivalent levels of internet technology across the country through broadband."
Mr Corbyn added that he is open to the possibility of bringing the UK's broadband network into public ownership if BT and other fibre optic cable providers did not commit to universal access under current regulation.
The government is currently aiming to give everyone a legal right to fast broadband, with speeds of 10Mbps as the absolute minimum.
However, BT recently questioned whether households should expect their broadband to be fast enough to enable them to watch several videos at once.
The company was quoted by the Telegraph as saying that much of what the government is asking for goes beyond the service that most people want or expect.
