Max Pearson presents a collection of this week’s Witness History episodes from the BBC World Service.

We first hear about Uruguay’s tale of David v Goliath - when a tobacco giant took South America's second-smallest country to court over its anti-smoking laws.

Uruguay’s former public health minister María Julia Muñoz describes the significance of the ban and its fallout.

And we shed some light on the wider history of the use of tobacco, its long and controversial history, with Dr Sarah Inskip, a bio-archaeologist at the University of Leicester in the UK.

Plus, the largest search operation in aviation history - ten years on, little is known of the fate of MH370 and the 239 people on board.

Also, Sister Rosemary Nyirumbe on how her sewing school in northern Uganda served as a place of rehabilitation for child soldiers escaping Joseph Kony’s Lord's Resistance Army.

Then, the Carnation Revolution - how Europe’s longest-surviving authoritarian regime was toppled in a day, with barely a drop of blood spilled.

Finally, in August and September 1939, tens of thousands of children began to be evacuated from Paris. Colette Martel, who was nine at the time, describes how a pair of clogs made her feel welcome.
