Dumfries and Galloway MP Richard Arkless has joined more than 100 other MPs in asking the Chancellor to invest in broadband in next week's Spending Review.
Mr Arkless says that without broadband in South West Scotland, businesses will be disadvantaged.
He has signed an open letter - along with other MPs - to the Chancellor of the Exchequer urging him to continue investing in fixed and mobile broadband as part of the Spending Review.
George Osborne MP is due to deliver his spending review to Parliament on Wednesday.
The letter was co-ordinated by the All Party Parliamentary Group for Broadband and Digital Communication.
