Biographer calls Queen's death a ''cataclysmic moment''

STORY: Speaking to Reuters shortly after the news of her passing was announced, he said ''the queen has been... the still point, the vortex of modern life for 70 years," adding the monarch unified society and created ''cohesion in our national life."

Dennison, who penned the biography ''The Queen'' released in June 2021, said Elizabeth will not only be remembered for her record-breaking 70-year reign, but also for her work ethic.

"She went on doggedly doing the job to the very best of her ability with total conviction and I think with love,'' he said.
