When I read it first Den, I thought the error was going to say it was 2/12...See the Mail, the Times and all the other usual suspects have issued apologies and retractions for suggesting that 1 in 12 Londoners were illegal immigrants.
Turns out the number was measuring the maximum number possible of something, rather than an estimate, the thing being estimated wasn’t illegal immigrants and the area used in the estimation wasn’t London.
Other than that it was all bang on though so you can see how they made a mistake…
