The story of Liverpool’s once thriving port is one of spectacular rise, and spectacular fall. In Liverpool and the Unmaking of Britain, the historian Sam Wetherell looks at the city post-WWII, as the decline in the port led to the poverty and neglect of its population, the deportation of Chinese sailors, and the discrimination against the city’s Black population. It’s a history as prophecy for what the future might hold for the communities caught in the same trap of obsolescence.

As manufacturing has declined in the UK it has grown exponentially in China, which is now known as ‘the world’s factory’. Dr Yu Jie is a senior research fellow at Chatham House and an expert in China’s economic diplomacy. She considers what the mega-cities that have emerged out of China’s rise, and the communities living in them, can learn from the history of Liverpool.

Corby in the Midlands was once at the heart of British steelmaking, with one of the largest operations in Western Europe. But once the plant was closed in the 1980s, the ‘clean-up’ became known as one of the worst environmental scandals, causing serious birth defects in the town. The four-part series, Toxic Town, written by Jack Thorne (on Netflix from 27th February) tells the story of the families as they fight for justice.
