Broadband access in the Scottish Highlands has been criticised by a local MP following the publication of a new investigation.

Danny Alexander, Liberal Democrat MP for Inverness, Nairn, Badenoch and Strathspey, has hit out at the region's coverage after a report from the BBC showed three million Scottish households do not have access to broadband speeds of 2Mb or more.

He told Highland News: "Today's BBC research is a salutary warning of the problems being experienced by broadband users across the country.

"There is a real frustration in some rural parts of the Highlands that broadband is still not available."

Mr Alexander added that proposed satellite broadband schemes for regions with poor access could prove "much more expensive" than previously anticipated.

Data from BroadbandSpeedChecker shows that the best high-speed internet coverage in Scotland is found in Glasgow, Edinburgh and the areas located between the two cities.
