One of the big talking points in the lead up to the royal wedding was whether Prince Harry would shave his beard off.
The ginger prince is working a lot of facial hair at the moment, and many people wanted him to get rid of it all ahead of the big day. However the groom wasn't having any of it and decided to keep it as it is. People on social media have slammed his decision, saying he isn't allowed to have it while dressed in an Army uniform.
But they're wrong.
As he is no longer a serving officer, Harry doesn't have to comply with the regulations.
In a statement, Kensington Palace said: “Her Majesty The Queen gave her permission for Prince Harry to get married in his uniform.” It is understood that the permission covered the fact that Harry has a beard.
Historian Hugo Vickers said the permission may also have been granted because Harry has retired from active service. The beard also caused a big row in November when he wore a full beard with a uniform of a senior Blues and Royals officer uniform at the Remembrance Day service. British Army rules forbid all beards, except in a few rare circumstances, such as when a soldier is suffering from a skin complaint, or has strong religious reasons for retaining facial hair.
Sikhs are not allowed to cut their own hair, and can thus retain their beards while in uniform, for example.
Special Forces or others on covert operations are also permitted to grow beards when behind enemy lines, but they would not wear them on parade.
There is also a tradition that allows a very small number of Pioneer Sergeants to wear a beard when on official duty, but members of the Queen’s personal guard have never been allowed to do so.
The Queen, Harry’s grandmother, is Colonel-in-Chief of the Blues and Royals, while the Colonel of the Regiment is Princess Anne, his aunt.
It is one of the two cavalry regiments of the Household Cavalry – the other is the Life Guards – and can trace its history back to Oliver Cromwell’s New Model Army of the 17th Century.
Throughout the centuries, officers have been known for their clean-cut appearances, although some occasionally grew moustaches and connected side-whiskers, especially when serving in Muslim countries.
The Royal Navy – in which Harry's father, Prince Charles, served – has always been allowed beards, but officers are told to shave them off it they are not full enough. Prince Harry left the Army in 2015, aged 31, after being commissioned as a Cornet, the equivalent of Second Lieutenant in the Blues and Royals, which after the Life Guards is the second most senior regiment in Britain.
Harry now concentrates on charity work and other Royal duties, but would normally be expected to abide by military regulations when in uniform.
