Professor Tim Evans of Middlesex University gives a fascinating analysis of Latin America's problems, with political instability and a growing macro-economic crisis. He also looks at the under-reported Vortex of Doom in South Africa, where there's a huge energy crisis and law and order is breaking down. Lastly, he turns to the UK, which now appears to be one of Europe's most nannying states when it comes to food, drink and health; is it a case of NHS demand management, he wonders?
