Scotland has the worst mobile phone coverage in the UK, according to a business group.

Improved 2G and 3G signals are needed to increase growth and encourage visitors to ­return to the country, the ­Federation of Small Businesses said.

Argyll and Bute, the Highlands and parts of Perthshire have the worst coverage according to the federation, which has responded to a Scottish Government consultation on plans to simplify the planning process for mobile operators to improve coverage.

The Government wants to make it easier to install phone masts and other equipment.
