The MoD has told Johnny Vaughan that a missile he bought as an ornament could be stolen.

The Space Cadets presenter got the 12ft air-to-air missile for £5000 at an antiques shop.

“I thought it would look great on my wall. But next thing, MoD cops called to quiz me about it," he explained. "I expected them to laugh and say it was safe."

Apparently, however, the missile should not have been in private hands – and it contains a secret satellite navigation system.

“They actually sounded very worried and said no one should have this missile as an ornament as it wasn’t decommissioned," continued Vaughan. "They said it held classified info that was dangerous in the wrong hands. We genuinely feared the warhead might be live."
