None of them have any power with regard to governing this country. The Queen just follows protocol. There are many royals but only a few of them are on the civil list. We actually support very few of them through our taxes.

The Royal Family have no powers. The British Government make the laws.

Too many. The only power they have is to spend taxpayers cash.

Too many! Mostly no good overpaid chinless wonders!

Far too many, are you offering to get rid ?
