Advertising watchdog the Advertising Standards Authority has upheld two complaints against false claims by objectors to a proposed wind farm in Cumbria. The complaints were brought by West Coast Energy, which hopes to build 27 turbines at Whinash near Tebay. The company objected to a leaflet distributed by opposition group "No to Whinash Wind Farm." The leaflet claimed that the presence of wind turbines has been seen to cause property values fall by up to 40% and that some tourist areas in sight of wind farms have seen business fall by 40%. The authority ruled that the opposition group had not been able to prove either allegation and told it not to repeat the claims. The group was asked to ensure it held "documentary evidence" to prove its claims in future advertisements.
