I produced my UK license, which Mr Plod took away to the jeep for examination by his colleagues. He came back declaring it was not a motorcycle license, which indeed it was and I pointed out the relevant category for him.
He then said I should have an International Driving Permit - this is the first time I haven't bothered to get one.
I told him that the UK license is universally recognised as the legal requirement and the International Permit is only a translation of the license into various languages and it is not a mandatory requirement, although possibly advisable in countries like India. He wasn't convinced and I could see that we were about to be asked for money. It was only when I suggested that we should all go into Panjim to Police HQ for clarification, that he told me to be on my way.
Here are a few tips if stopped by the police.

1. Switch off the engine and put the keys in your pocket. If Mr Plod has your keys - you are going nowhere.
2. Be courteous and helpful. You don't want to antagonise these guys.
3. Make sure that you have no more than your prepared to pay as a bribe in your wallet. Secret the rest of your money elsewhere.
4. If you're brave enough - don't stop - they probably won't chase you, because there's always an another mug just behind you.
