County counsel, anyone?

Some of you have kindly pointed out that a few of our towns are shown located under old county names. Apologies to all those concerned. We're trying to rectify this now. Welsh and metrpoloitan counties we should be able to correct but, for other places, where new administrative responsibilities don't synch with traditional borders, the problem is more difficult. For instance, Romford doesn't have a London post code but, administratively speaking, it's not in Essex. So should we have 'Romford, London' or 'Romford, Essex'? We could drop the county names altogether as they're not used for mail direction any more. But then, how would we deal with the four Newports, for instance?
