Research by the charity English Heritage suggests it may have found a portrait of England's shortest-reigning queen Lady Jane Grey

Researchers believe they may have identified the only known portrait of Lady Jane Grey, the so-called “Nine Days Queen,” painted before her death.

She was Queen of England for just nine days before being executed at age 17, marking the shortest reign in British history. Now new research suggests a portrait that has gone on display in Britain could be the only image of Lady Jane Grey painted in her lifetime,
