Dame Joanna Lumley said: “Timothy really will be a huge loss, obviously, to Pru, but I think a huge loss to everybody who came to love and respect them, not just the general public, but particularly those who live with dementia.
“I think between them, Timothy and Pru did an amazing job of convincing people that dementia was not something that you should be always afraid of, but something that you could embrace and live with and live with well,” she added on Times Radio.
