Tying up our 'summer' specials (now autumn), part 4 of 3 (whoops) is this special on radio as propaganda in World War 2. The non-BBC story.

Sefton Delmer sent black propaganda from near Bletchley Park into Germany, as Lord Haw-Haw did the opposite, sending radio propaganda from Germany back into Britain.

Meanwhile Hilda Matheson (remember her from two episodes ago?) was sending transmissions from the JBC - the Joint Broadcasting Committee - in Woburn Abbey, also near Bletchley Park. And somehow between here, there and everywhere, bouncing between Germany and Britain and across Europe, somehow involving MI5 and Ian Fleming, there's that man again... Peter Eckersley.

It's quite a tale, and here to bring it to you is Tim Wander (author of 2MT Writtle and From Marconi to Melba) and Edward Stourton (author of Auntie's War).

Plus with the passing of Queen Elizabeth II, we bring you the first broadcast from the most broadcast person in the world (I think) - aged 14, Princess Elizabeth on The Children's Hour in 1940.

Next episodes from here? Well it's the end of our summer specials, but the start of our centenary specials! The regular episodes in our 1923 timeline will return in the New Year. But first, a few episodes commemorating and celebrating 100 years of British broadcasting - including an episode on 100 Years in 100 Minutes... and for that we need you!

Record a short voice memo (20-40 seconds) on ANY element, moment, landmark or programme from the last 100 years. Send to me - paul at paulkerensa dot com. Be on our centenary special!
