I get that you don’t like the YouGov outcome as it doesn’t support your point of view, but it’s reliable, statistically significant sample from a well known and trusted research organisation.
This makes me laugh. YouGov pay people to do surveys - badly. It took me 18 months to 'earn' 18 months. I soon learnt how to skip through them very quickly without reading the questions. I would imagine most regular YouGov survey takers do the same. It would pay pennies per hour if you read through them all carefully. There are much better research organisations. I take any data quoted from YouGov with a pinch of salt. And that sample size is absolutely tiny - no where near large enough to draw any reasonable conclusions.
Yes, people will turn out to see the royals - they very rarely visit the area I live in so it is something of a novelty. This does not mean that people would be happy to see millions spent on pointless pomp and ceremony - especially so soon after the funeral and with the coronation coming up. There is little enthusiasm for a ceremony in Caernarfon from people living there. In any case, if it was held there again places in North West Wales are so cash starved that they would struggle with the infrastructure - not enough hotel spaces for a start. I would prefer that any millions set aside for ceremonies be actually spent on services people so desperately need.
Nothing against William and Kate. I quite like the royal family, but pretending he is suddenly all about Wales and Welsh is a nonsense. He and Kate lived on Anglesey for a while and he had plenty of opportunity to make more of an effort then. Yet last week we have the press fawning over the fact that he has learnt a handful of Welsh words. Non Welsh speaking children in their first year in nursery school have more Welsh in their vocabulary than that.
If he and Kate took the title of Prince and Princess of Wales seriously they have had years to demonstrate that. I see little evidence that it is anything more than a title for them.
