Empty shelves are becoming commonplace. And prices are rising. Charmaine Cozier explores the role that the pandemic, and a sudden demand explosion, have had on supply chains. Around the world workers are being slow to return to their jobs, the container shipping industry is struggling to get goods to their destinations and manufacturing disruptions are causing a reduction in vital components. And in addition to the pandemic, extreme weather events have resulted in ruined harvests. How long will it take for things to return to normal?

Energy prices are spiking in the UK, as gas prices soar and wind turbines stop spinning. The UK's shift to green energy is the envy of the world, but Tanya Beckett asks if there is a lesson for other countries in how to go about it.

For decades China's economic growth has been the envy of the western world. But current signs suggest all is not well.

In May, the Biden administration surprised the world by saying it would not object on an intellectual property waiver for Covid-19 vaccines.
