A German submarine which sank off the coast of Folkestone in 1918 is to be moved because it poses a threat to shipping.

The U-boat is a designated war grave and saw the loss of 28 crewmen when it collided with a mine.

It currently lies near the Varne bank just 23 metres below the surface.

Although the wreck has been undisturbed since it sank the increasing number of vessels operating in the Channel means the wreck is reducing the avaliable sea room.
