The Transport Secretary Patrick McLoughlin: "There are too many unnecessary signs blotting the landscapes of our towns and cities. That is why I have published new guidance, to help encourage local authorities to make old, confusing and ugly signs a thing of the past.

"They are a fantastic example and I urge other councils to think about where traffic signs are placed and whether they are needed at all."
