The UK only has 1 official language. And it's Welsh.
What the frack??? Can you please elucidate on this one, Hiram?

Well, the United Kingdom is made up of four countries, Wales, Northern Ireland, Scotland and England. So technically, if they vote to leave the United Kingdom, they can and they have at present the autonomy to decide if they want an official language or not in each respective country. Canada has two official languages, English and French and Provinces can vote to secede by vote which Quebec almost did in the 1990's. The USA has no official language even though English is the predominant language and thanks to the Americal Civil War, 1861-1865, not only was slavery forever forbidden from ALL the States of the Union but also any of the Territories (colonies) of the USA but another issue that was ended due to the Civil War is the fact that no State can vote for secession either. Abraham Lincoln, 16th President, set the precedent that if any state tries to secede, the Federal Goverment can use whatever force it wants to keep that insurrectionist State within the Union. That is why the Army of the Northern States was called the Union Army and the Southern States was called the Confederate Army.
