Dumfriesshire Clydesdale and Tweeddale MP David Mundell has expressed delight at the rejection of plans for sand and gravel extraction at Overburns, near Biggar.
The decision was taken by the Scottish Government Planning and Environmental Appeals Division after the applicants appealed against the latest rejection by South Lanarkshire Council of controversial quarry proposals.
Mr Mundell has fought against various extraction plans on behalf of constituents concerned about the development in what is a rural and scenic area.
He said: "I welcome this entirely logical and well thought out decision rejecting quarry plans at this site.
"I have worked with the local residents and council colleagues over a number of years to repeatedly oppose such development attempts, which were causing a great deal of worry to local residents.
"There is a history of proposals being brought forward at this location and I will continue to monitor the situation. However, I hope this is now an end of the matter.
"We must protect this particularly beautiful and environmentally important part of Clydesdale and any further threats of disruption to the community."
