FAILURE to invest in Scotland's economic infrastructure will have a negative impact on national finances, a new report suggests.

The report, entitled Delivering Firm Foundations for the Future, comes from N-56, a business-led initiative made up of both foreign and domestic economists.

They suggest Scotland's economy is underfunded and should be bolstered to echo the commitment of other "advanced" economies.

The report claims that if Scotland invested an extra £400 million per year, it would provide a £1.1 billion boost to the economy.

Some of the measures include a development of an airport hub and freight port services as well as extending the high speed rail network to Scotland, and improving the road and rail connections between Scottish cities.

In so doing, the report argues that Scotland would thrive much like Finland, Switzerland and Singapore.
