This raises more questions but doesn't provide any answers.
From the transcript it is clear that Radio Cornwall is more than happy to find some banal answer to the question as to why Cornwall's flag was flown alongside those of England, Wales and Scotland. Why is this if they are supposed to represent Cornwall?
If the answer that Radio Cornwall have received is correct then surely there should have been a lot more flags flown on the Gloriana. If everyone who contributed anything to it being there was represented by a flag then there were probably a few people a tad unhappy that their contribution hadn't been recognised?
