There will there always will be that faction which wants to end the monarchy, but if we consult the polls taken of the British people over the years, the popularity of the idea was significant earlier in her reign but now it's much smaller. The response to Diana's death was one factor in that change, but only one of a number.
Yep, it's just a question of how many it would take to actually abolish the monarchy and whether the republican groups have any realistic chance of gathering that much support.
Since public opinion seems less hostile to the concept of Queen Camilla (even if technically Queen Consort Camilla) than it has been in years gone by that suggests Charles won't face an immediate uphill battle. I wonder if that was anything more than a masterstroke by the Queen to make it clear it was her decision rather than Charles' decision to grant Camilla the title.
Exactly. It's supposed by many people that all the ceremonies, etc. are a waste of money, but cooler heads have explained that this is a major attraction for tourists from all over the globe.
Some other countries seem to suggest that we don't specifically need the monarchy - France still gets tourists to see the buildings even though they have done away with their monarchy. Personally I think having actual people behind the buildings makes a lot of sense, especially when those people help represent a lot of charitable causes.
I think the relatively recent process of seriously pruning the Civil List helps deflate the argument about wasted money. It's not as if the Royal Family was expensive before relative to other things (welfare budget, defense budget etc) but pruning the costs further just means they cost even less than before and also gets rid of the ones seen as hangers-on.
