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.

A mysterious portrait of a woman now on public display could be the only painting of Lady Jane Grey before she was executed, according to research. Lady Jane was Queen of England for just nine days, from July 10 to July 19 1553,
