主播大秀

Max Pearson presents a compilation of this week's Witness History programmes from the 主播大秀 World Service.

Sir Trevor McDonald reflects on the 主播大秀's first black producer, Una Marson, and her legacy in the development of the 主播大秀 Caribbean Service.

Also, how the 主播大秀 managed to broadcast through the Iron Curtain, Colombia's false positives scandal and the incredible rescue of 33 miners trapped in Chile.
