The story is this - and apparently happened in 1980:
Shilton was arrested for drink-driving after being found at 5am in a country lane with a woman called Tina in his car. When Tina's husband Colin arrived he said the pair were partially clothed. Shilton hurriedly drove away and crashed into a lamppost. He admitted 'taking a lady for a meal' and was fined £350 and banned from driving for 15 months. He then had to endure countless terrace chants of 'Shilton, Shilton, where's your wife?'
