Official mistakenly emailed details of G20 leaders to Asian Cup football organisers

The personal details of world leaders such as US president Barack Obama, German Chancellor Angela Merkel and British Prime Minister David Cameron, including passport numbers and visa details, were accidentally leaked to the organisers of a football tournament last year.

The breach, which came during the G20 Summit in Australia last year, included data from 31 world leaders being sent to the wrong person by the Australian Department of Immigration.
