David was my friend from uni. A totally brilliant human: kind, generous, funny, ferociously intelligent. It's hard to process that a light so bright could be so unexpectedly extinguished. My thoughts are with all those who loved him.
It is with great sadness that we share the news of the passing of our colleague, David Knowles.
David was a talented journalist and a much-loved friend and a colleague. He will be greatly missed.
