This weekend's elections will determine the makeup of Germany's parliament - and set the country’s course for a new, post-Angela Merkel era. German politics tend to be less adversarial, less personal and polarised than in many European states – although there’s still plenty to be argued over. So far the campaign has stuck to the issues – there have been no notable gaffes or dramatic confrontations. But it is a close race and opinion polls have swung wildly. After this year’s catastrophic flooding and the economic shocks of the pandemic, voting for “more of the same, please”, is not really an option. Jenny Hill seizes up how many fresh ideas are on offer for German voters.

There's an epidemic in the USA which has cost around half a million lives. Not Covid - this is a drug epidemic. And it was caused by an addiction brought into American homes by major, reputable pharmaceutical companies; They sold opioids as painkillers, despite – as it has transpired in court - being aware that they could be highly addictive. So, patients prescribed them wanted more and more. If their supply of prescribed opioids ran out, some were so hooked they used heroin to ease their withdrawal symptoms. Oxycontin was the drug implicated in many of the cases of opioid addiction. But now the company which made Oxycontin has been told it won’t be prosecuted. Indeed, the Sacklers, who own it, will remain one of the wealthiest families in America - protected from prosecution. Daniel Thomas has followed the Oxycontin story and has met some of those caught up in it.

The long years of armed struggle in Colombia are supposed to be over – with many of its rebel factions and paramilitaries officially demobilised and their recruits sent on their way. The largest guerrilla force, known as the FARC, is now signed up to a peace deal with the government it had fought for decades. But the ghosts of the country’s insurgencies are still everywhere: there are over eight million people in the country who’ve had to flee their homes in areas controlled by armed groups. Many thousands more went missing during the conflict, whose fate may never be known. But some of their relatives never give up looking for them. Mathew Charles heard the story of one woman’s life in a time of violence.

With a growing population of more than 1.3 billion, and a burgeoning middle class, India is facing an energy crunch in the near future. Its needs are set to rise more than any other nation’s during the next 20 years, according to the International Energy Agency. India is currently the world’s third-largest emitter by country and it still relies heavily on coal to keep its industries running. As other nations are urged to phase it out, how easy will it be for such a fast-growing AND fast- developing nation to ditch one of its favourite fuels? Rajini Vaidyanathan explores the dilemma in Odisha state.

Ireland has always been renowned for its conversation – the ease with which people, often complete strangers, fall into talk, relate stories or debate the issues of the day. One recent topic has been the latest population statistics: in Ireland, unlike many European Union countries, the population is increasing - with numbers topping five million for the first time since the middle of the nineteenth century, when famine caused millions to emigrate. There’s been many a boom and bust since then. But now many Irish exiles are coming home. Kieran Cooke, having a drink at his local bar, came across some interesting returnees.
