For those of us who remember the Brexit campaign, it all sounds eerily familiar. Argentina’s new leader, Javier Milei, wants to leave South America’s common market, Mercosur. He doesn’t want his trade and economic policies to be tied into his neighbours’, and clearly thinks Argentina can do better on its own.

Argentina’s economy is in a catastrophic condition right now, and Milei would undoubtedly like to sell his citizens an easy solution. Exactly how an Argentine exit would affect trade with some of its biggest partners is as yet unclear. But exiting Mercosur would definitely throw up some significant challenges.

As world leaders try to agree ways to limit climate change at the COP28 UN summit this week, we hear how half of carbon emissions globally come from the richest 10% of people – and in the UK that includes people earning more than £32,000. But these figures can be misleading. Plus, why men in 19th century west Wales dressed up as women to protest taxation.
