£23m of parking fines 'may have been unlawful

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 16 councils still have no authorisation for these signs, while others went years without.

Some boroughs insist a later judgement made tickets enforceable.

BBC London's Marc Ashdown spoke to parking campaigner Barrie Segal and specialist motoring lawyer Neil Davies.
