Prime Minister Narendra Modi is among 31 world leaders whose personal details were inadvertently compromised at the G20 summit held in Australia last year, a media report said today.

An email error by an employee of Australian immigration department accidentally sent the passport numbers, visa details and other personal identifiers of the heads of government attending the G20 Leaders' Summit in Brisbane last November to the organisers of the Asian Cup football tournament, the Guardian reported.

Besides Modi, US President Barack Obama, Russian President Vladimir Putin, German Chancellor Angela Merkel, Chinese President Xi Jinping, Japanese Prime Minister Shinzo Abe, Indonesian President Joko Widodo and British Prime Minister David Cameron were among those whose details were exposed, the report said.

The Australian privacy commissioner was contacted by the director of the visa services division of Australia's Department of Immigration and Border Protection to inform them of the data breach on November 7, 2014, and seek urgent advice.
