Is debt essential for economic growth? We look at the economics and morality of debt. Should countries burdened with huge debts be forced to repay them in full? And, if it is fine for an individual to borrow large sums to buy a house, why shouldn’t governments do the same to finance employment schemes or large infrastructure projects? Owen Bennett Jones and his expert panel are in front of a live audience at the How the Light Gets in Festival in Hay-on-Wye to discuss the problems of debt.

The use of mercenaries in warfare has a very long history, and still very much in evidence today. African governments seeking to push back rebel insurgents often employ mercenaries to carry out the task. From Yemen to Syria, mercenaries are directly involved in combat roles. And defence and training work once carried out by national armies is now often done by private military contractors. In this week’s Newshour Extra, Owen Bennett Jones and his guests consider the role played by these privatised forces fighting someone else’s war.

Donald Trump and Hillary Clinton are seen as the most unpopular candidates to have ever stood for the presidency of the United States. So why is it so difficult for a third party candidate to break through and make a real impact? Owen Bennett Jones and his guests discuss whether the US political system, trumpeted as a shining beacon of democracy across the world, really does give the voter the best choice.

Tensions are high in the disputed region of Kashmir. Weeks of protest in the Indian-administered part have left dozens dead and hundreds injured many of them blinded by crowd-control pellets fired by the Indian army. Kashmir has been a dangerous flashpoint between nuclear-armed neighbours India and Pakistan for more than six decades. Currently a boundary – the Line of Control – divides the region in two and it remains one of the most heavily militarised zones in the world. In this week’s Newshour Extra, Owen Bennett Jones and his guests discuss the future of Kashmir and the options for a political resolution to the highly complex dispute over the region’s sovereignty.

How comfortable would you feel getting into a vehicle driven by a computer? Versions of the driver-less car are now a reality, already on public roads in Singapore and as a taxi service in the city of Pittsburgh in the United States. But can a computer safely navigate complex, unpredictable situations in poor visibility? And can government legislation keep up with the fast-changing pace of technological progress? Owen Bennett Jones and his guests consider the safety of this new technology and who should take responsibility when things go wrong.

The battle of Stalingrad was arguably the most important strategic battle of the Second World War. The Germans and their allies were eventually defeated by Russian forces after a long, brutal conflict and siege of the city. Aleppo has been described as Syria’s Stalingrad – the country’s largest city, its commercial and trading powerhouse – with rebel held areas under siege by government forces and much of it reduced to rubble. This week on Newshour Extra we’re devoting the programme to the city of Aleppo and its strategic significance in Syria’s long and bloody civil conflict. Join Owen Bennett Jones and his guests both from inside and outside the city, along with the politicians currently meeting in London to discuss diplomatic solutions to bring the war to an end.

In the UK most payments now made do not involve cash. Rather than handing over notes and coins, most transfers are made electronically. South Korea's central bank has a target of eliminating cash by 2020 and many other countries want to reduce the amount of physical currency in circulation as it is quite costly. So is cash going to be a thing of the past? Owen Bennett Jones and his guests discuss the possibility of a truly cashless society.

There was widespread shock and international condemnation when the Islamic State group destroyed the ancient Syrian site of Palmyra in 2015. But why does preserving heritage matter? Does an exploration of the past always bring unity, or is there a danger that preserving history can fuel divisions? And are we in danger of prioritising culture over human life? Join Owen Bennett Jones for a special edition of Newshour Extra recorded in front of a live audience in Edinburgh, with guests from the Edinburgh International Culture Summit.

This week it was announced that London was getting a new team of specialist police officers to investigate online hate crimes, including abuse on Twitter and Facebook. But how widespread is the problem, and is getting law enforcement involved the best way to tackle it? In this week’s Newshour Extra, join Owen Bennett Jones and his guests as they discuss why the abuse happens, and whether there should be limits to free speech on social media.

Is India’s caste system a discriminatory and divisive anachronism that’s had its day, or does it provide stability and order in a complex society with its roots in ancient traditions? Members of the low-caste Dalit community – once known as ‘untouchables’ – are marching in the state of Gujarat following a spate of recent attacks against them. They say they’ll boycott their designated tasks within the caste system, which include the manual cleaning of sewers and the disposal of dead animals. Join Anu Anand and her guests as they discuss whether positive discrimination on the basis of caste works – or whether it’s time to abolish the caste system altogether.
