Who are the current lord and lady derby?

As of my last knowledge update in October 2023, the current Lord Derby is Edward Stanley, the 19th Earl of Derby, who succeeded his father in 2021. The current Lady Derby is his wife, Emily Stanley. They are known for their contributions to various charitable causes and their involvement in the family estate, Knowsley Hall, in Merseyside, England.
