The Duke: A Portrait of Prince Philip drew 5.3m, or 23.2% of the viewing audience, from 9pm. ITV1's average for the slot so far this year is 4.3m (17.5%).

On Channel 4 at 9pm, 1.5m (6.3%) tuned in for one-off documentary The Dinosaur Mummy, while Teen Mum High, BBC Two's new factual entertainment title, drew 1.3m (5.8%). Paul Merton in China, repeated on Five, interested 641,000 (2.7%).
