When the thirteen year old Margaret Tudor, eldest daughter of Henry VII and his wife Elizabeth of York, married King James IV of Scotland in a magnificent proxy ceremony held at Richmond Palace in January 1503, no one could have guessed that this pretty, redheaded princess would go on to have a marital career as dramatic and chequered as that of her younger brother Henry VIII.

Left widowed at the age of just twenty three after her husband was killed by her brother's army at the battle of Flodden, Margaret was made Regent for her young son and was temporarily the most powerful woman in Scotland - until she fell in love with the wrong man, lost everything and was forced to flee the country. In a life that foreshadowed that of her tragic, fascinating granddaughter Mary Queen of Scots, Margaret hurtled from one disaster to the next and ended her life abandoned by virtually everyone: a victim both of her own poor life choices and of the simmering hostility between her son, James V and her brother, Henry VIII.
