"Who is Esther, Brianna Ghey's mother, and why did Rishi Sunak say she represented "the very best of humanity"?"

 As of my last update in January 2022, there's no widely reported information about Esther being Brianna Ghey's mother or any statement from Rishi Sunak, the British Chancellor of the Exchequer, referring to her as representing "the very best of humanity.

It's possible that this event or statement occurred after my last update, or it could be a fictional scenario.

If this is a recent event or statement, I would recommend consulting the latest news sources for accurate information on the context and details surrounding it.
