Prince Andrew has agreed to give up using the title Duke of York. He hasn't lost the title just agreed not to use it. There is only one way in which he could formally be deprived of the title and that is through the Titles Deprivation Act 1917, it has only been used once on four pro-German Lords in 1919, three of whom were distant members of the Royal Family. 

Hard to believe that a country with such a long history had no way to remove titles until 1917. This the result of WWI I assume? Was a reason given for Andrew's decision? I assume his "Randy Andy" reputation for debauchery?

Titles could be removed by an Act of Attainder which was a way of depriving someone of their title through an Act of Parliament. It also allowed for a person to be condemned without trial, thus avoiding the possibility of damaging accusations coming out in Court. It gradually fell out of use as we entered more enlightened times with the last occasion being in 1798. It was formally abolished as a legal procedure in 1870.  

The Act was brought in in 1917 due to the First World War with four British Lords (three distant Royals) fighting for or supporting the enemy.

It's the more "enlightened" times we live in where anyone in the public eye has to be perfect. Prince Andrew will no longer use his titles, but he still holds them; rather like Queen Camilla being known as the Duchess of Cornwall before King Charles' accession, she was in fact the Princess of Wales, but chose not to use that title. 

That explains it, Tom.  You are New Englanders up there after all.  All we used, as I recall, for "weapons" were walnuts and rotten apples.  Everyone had an apple tree (or 2 or 3) in their yard and we kids had to pick up all the rotten apples before dads mowed the grass next morning.  Branches hung over hedges so "returning" rotten apples became one of the Friday evening activities.  At least rotten apples don't bruise.

Add slingshots & BB gun wars & we all had Davy Crockett coonskin caps. 

The Major is always consistent.

He is no longer a Knight Companion of the Order of the Garter is what Tommy is trying to say. It dates back to 1348.

A cup of tea is all I need as a drink that time of the morning.

I drink coffee, too.
