UK vs Great Britain

Since all British passports are issued in the Queen Elizabeth II's name, she herself doesn't have one.

Passports issued by the UK, Sweden and Finland offer visa-free travel to more countries than any other passports.

The terms "UK" and "Great Britain" are not interchangeable: the United Kingdom includes Northern Ireland, while Great Britain does not.

The UK is the only country not required to name itself on its postage stamps. 

Of all the countries that celebrate an independence day,  
58 are independent of the UK,  
26 of France, 
21 of Russia and 
21 of Spain.
