Secret documents signed by the former British Prime Minister Winston Churchill, including plans to build a tunnel between England and France in 1914, have been sold for a total of 7,400 pounds at an auction in the United Kingdom.
The original printed note 'The Channel Tunnel document' by Churchill as First Lord of the Admiralty discussing the feasibility of building a tunnel and considering the risks posed if France were to become England's enemy in 1914 was sold for 2,400 pounds.
In the document, dated June 12, 1914, Churchill expresses his opinion as to how the country could be defended in the event of an attack, according to the Mullocks auction house.
"The tunnel should be brought to the surface of the sea not less than a quarter of a mile from the shore and the railway should run from the tunnel mouth to the shore on a bridge," he wrote in the document.
No other version of this document signed by Churchill is in existence.

The documents were sold for 600 and 4,400 pounds respectively.
