Unfinished business? The 22 countries worldwide that Britain's not yet invaded

Britain has still 22 countries to invade

According to a new study, of the 193 countries in the world, Britain has invaded all but 22. The figures come from a new book by Stuart Laycock called All the Countries We've Ever Invaded and counts everything from full-scale invasions – Afghanistan – to piratical expeditions backed by the government – Ecuador.

Of the list of 22, several offer inviting pretexts for a little light invading. Paraguay, I'm told, is lovely at this time of year. The Marshall Islands have the most attractive beaches. And just think of the art in the Vatican City. Might leave Monaco, though – we don't need any more tax-dodgers.
