Max Pearson presents a collection of this week’s Witness History episodes from the BBC World Service. This week, we’re looking at the birth of a new African nation – Zambia - in 1964, and find out how the country got its name. We also learn more about life after independence with our guest Dr Alfred Tembo, head of history of the University of Zambia. Elsewhere, two survivors of a series of terrifying gun attacks in Mumbai talk about their experiences. And there’s a look back to 2003, when the worst heatwave in centuries caused thousands of deaths across Europe, and led to a health crisis in Paris. Plus, we hear extracts from the lost memoirs of Manchester United goalkeeper Les Sealey. He recorded them before his death and the tapes were discovered years later. And finally, the invention of bubble tea, a creation that would change the tea drinking world. The first cup was sold in a tea shop in Taiwan in 1987.
