Prince George has an official title which he only bears because his great-grandmother the Queen decided to step in and change the rules. Thanks to her, he is now officially known as His Royal Highness Prince George of Wales (Previously Prince George of Cambridge). His full name is George Alexander Louis, with Louis in honour of King Charles III's mentor Lord Louis Mountbatten, who died in an IRA bombing in 1979 - his brother's namesake.
Prince George was given the HRH title after the Queen intervened to overwrite a rule put in place by King George V, the Express reported. In 1917, he set out new guidance on which royals were allowed to have titles - and who was too far down the line of succession to qualify for one.
