Although Mr Freeman has previously used postal delays to get celebrity clients off motoring offences, he is calling for authorities to close the loophole. He said: "Sending out letters in this day and age really does not make any sense especially when the Royal Mail is going out on strike. "It is possible lots of alleged speeders are slipping the net because of the vagaries of our postal service." Mr Freeman called for the system to be changed "urgently" with more industrial action likely to come.
