Britain's Duke and Duchess of Cambridge's baby could be "in danger" of kidnap.

Prince William's childhood bodyguard Ken Wharfe has warned that the royal couple's plan to spend the first six weeks after their child's birth in Berkshire with Catherine's parents instead of at a royal residence is a risky move.

He told LOOK magazine: "Kate's baby could be in danger. Given the political state of the world and the vulnerability of the royals, they need a lot of protection. In this terror-ridden world of ours, there's a real

risk of kidnap for this child.

"The world is a much more dangerous place than it was 20 years ago, when we would take William and Harry out. And even then, there was a large protection team with the sole responsibility of looking after them. There are going to be people in every conceivable tree and bolthole, waiting for their baby to be pushed out in a pram."

Ken insists Catherine's parents Carole and Michael Middleton's £4.85 million estate isn't safe enough and believes it will cost a fortune to provide the baby - who will be third in line to the throne - with adequate security.

The former royal aide added: "They may have some security equipment at the house, but there is absolutely no way they could put in enough in the short time she is likely to stay there. What they'll have to do is surround themselves with police, which could be a multi-million pound operation."
