mso489 - with respect to Jay, I don't know where he got the idea that flying the union flag was not allowed without permission. This from the official (Crown) rules on it:
1. Flags Not Requiring Consent
...
The flag of Saint David.
The flag of Saint Patrick.
The flag of any administrative area within any country outside the United Kingdom.
Any flag of Her Majesty's forces.
The Armed Forces Day flag.
Any country’s national flag, civil ensign, or civil air ensign.
The flag of the Commonwealth, the European Union, the United Nations, or any other international organisation of which the United Kingdom is a member.
A flag of any island, county, district, borough, burgh, parish, city, town or village within the United Kingdom.
The flag of the Black Country, East Anglia, Wessex, any Part of Lincolnshire, any Riding of Yorkshire, or any historic county within the United Kingdom.
I note that this means that Jay, being from Cornwall, would be permitted to fly the Cornish flag! It also means that an American, for example, could fly the stars and stripes.
There are some rules pertaining to the erection of poles, but these are mainly for reasons of safety.
Hope this clarifies that point.
A further point though is worth making: the national flag in the UK is NOT the primary symbol of statehood as it is for Americans. In the UK the primary symbol is the Crown, with the flag being only a secondary symbol. This is why British people, generally, do not view the national flag in quite the same rosy way as you guys do across the pond.
