Fibre-optic broadband can give the UK economy a much-needed boost during the recession, according to David Cameron.
The Conservative party leader will make the assertion as he lays down policies relating to 'green technologies' - a sector he says Britain is lagging behind in.
Mr Cameron will draw attention to the snail-pace broadband speeds in Britain compared to other countries in the West and Far East.
He is expected to say today: "Fibre optic broadband is changing the way people work and do business, and it has the potential to completely transform our economy.
"It could open up new markets for our creative industries, promote innovation, create new, family-friendly jobs as people can work from home - and help reduce carbon emissions."
The news comes after prime minister Gordon Brown singled out public investment in broadband as a way that the government can help Britain take the blow of the recession.
