The UK government has recruited M&G Investments and Amber Infrastructure to run a £400m fund investing in projects to plumb broadband cable through the UK's streets.

The government hopes its £400m investment will encourage private-sector investors, such as pension funds and insurers, to stump up another £600m, adding up to "over £1bn for full-fibre broadband" and "better connections across the country", according to a statement from the Treasury.
