Err, I'm afraid your wrong.
It's correctly called the "United Kingdom of Great Britain and Northern Ireland" Great Britain is an island, only incorporation England, Scotland and Wales, as hazzle correctly said. It does not include the Isle of Man, Isle of Wight, Ireland etc.
However, anyone within the UK can be correctly called "British" but not necessarily in "Great Britain".
