A manuscript believed to have been written by a doctor who examined Napoleon Bonaparte's body could put an end to the theory he was murdered.
Many historians have claimed the French Emperor was poisoned with arsenic, although the official cause of his death in 1821 was stomach cancer. The document found in a Scottish cottage seems to confirm the official theory of his death while in exile.

It will be auctioned by Thomson Roddick & Medcalf of Carlisle on Friday.

Steve Lee, military auctioneer at the firm, said he was convinced the document is genuine. He said: "We believe it is an extremely significant document which puts an end to the theories that Napoleon was murdered.

"Unfortunately the author did not sign his report, but he describes Napoleon's insides in great detail and the cancer.

"We honestly don't know what it will go for, it may fetch just a few hundred pounds and be of limited interest, or it could go for five figures to a specialist collector."

The paper is believed to have been written the day after Napoleon's death on May 5, 1821.
