Almost 350,000 parking fines - totalling an estimated £23m - may have been unlawfully issued to motorists in London, a BBC investigation has found.
In 2010 a ticket issued in a suspended parking bay was ruled unlawful because Camden Council did not have authorisation for its signage.
Now the BBC has learned 14 councils still have no authorisation for these signs, while others went years without.
