Personalities including Mark Strong, Bear Grylls, Dr Dr Christian Jessen, and Richard Whitehead have lent their support to The Royal British Legion's #ThankYou100 campaign, marking the centenary of the end of the First World War.

Catherine Davies, Head of Remembrance at The Royal British Legion, commented, 'It’s great to have such well known personalities lend their time and support to such an important cause... Our "Thank You" movement, which has been running since the summer, has been created to honour not just those who fought and died in the First World War, but everyone - military and civilian - who served, sacrificed and ultimately changed our world for the better'.
