The UK Conservative Party are also known as the Tories, a word that comes from the Irish 'toraidhe', meaning a highwayman or brigand.
It was adopted in the late 1670s as an abusive nickname for supporters of James, Duke of York, who later became James II.
Between 1809 and 1997, there were 22 Tory leaders of whom only one did not become Prime Minister.
He was Austen Chamberlain, who went on to win a Nobel Peace Prize.
Between 1997 and 2007, there were three Conservative leaders, none of whom either became Prime Minister or won a Nobel Prize.
"I never meant to say that the Conservatives are generally stupid. I meant to say that stupid people are generally Conservative. I believe that is so obviously and universally admitted a principle that I hardly think any gentleman will deny it."
John Stuart Mill, 1866.
