A WWI spy story in which the late Rhodri Morgan investigates a Welsh connection to Lenin.
Lloyd George's Welsh Spy is a spy story set against the backdrop of the First World War and the Russian Revolution.
In the months before his death earlier this year, former First Minister Rhodri Morgan investigated the life of his great uncle Morgan Watkin, whose secret wartime service reads like something from a novel by John Le Carre.
Rhodri's search for the truth took him across Wales and to Switzerland, and found him uncovering the life of a gentleman spy.
As well as being a historical detective story, the programme throws light on the mysterious ways of the developing secret service during the First World War and on the way Lloyd George used Welshmen to help him become a successful war leader.
It also tells the story of Lenin in Zurich, and his remarkable return to Russia by sealed train - and the effect that would have on the war and on the Twentieth Century. Prof Dr Christian Koller and Dr Nada Boskovska, two of the world's leading experts on Lenin's exile in Switzerland, guided Rhodri through the story.
