‘Compelling evidence’ suggests figure is Lady Jane Grey, making it only known depiction made before 1554 execution

She was known as the “nine-day queen” and was used as a pawn in the ruthless ambition that defined the Tudor court. But for centuries, historians have struggled to find a single portrait of Lady Jane Grey that was painted during her lifetime.

Now, research by English Heritage suggests a mysterious portrait depicts the royal who reigned over England for just over a week in the summer of 1553, and who was executed less than a year later.
