As the Queen's coffin left Buckingham Palace for the last time on Wednesday, many saw that the coffin was draped in the Royal Standard flag, alongside the Imperial State Crown on a velvet cushion with a wreath of flowers atop, and carried on a gun carriage of King's Troop Royal Horse Artillery.
Through the years, the composition of the Royal Standard has taken various forms. In today's Standard, there are four quarterings - England is represented with the three lions passant in the first and forth quarters. Scotland is represented with a lion rampant in the second quarter and Ireland is represented with a harp.
But Wales is not represented on the Royal Standard flag, just as it is not represented in the Union Jack (also known as the Union Flag). The reason for this is down to decisions made hundreds of years ago.
