The Ministry of Defence (MoD) has denied Reuters reports claiming it has banned high-capacity personal storage devices, such as iPods.

An MoD spokesman told the BBC that this was "not the case", adding: "We have a flexible management approach in regards to iPods and similar devices that can move data from official systems."

The MoD added: "Risks are assessed in each area, and, when appropriate, measures are taken to mitigate that risk."
