Just over 100 years ago the island of Ireland was partitioned. It created an independent catholic free state in the South and a majority protestant one in the northeast called Northern Ireland that remained a part of the United Kingdom. For many catholics and nationalists the goal of a united Ireland remains. For most protestants and unionists the division has been key to preserving their British identity. But the demographics are changing in Northern Ireland. The most recent census show catholics outnumbering protestants for the first time, though still short of being the overall majority. There’s also been a rise in support for Sinn Fein, the political party that supports a united Ireland. Any question about whether Northern Ireland remains part of the UK or becomes part of a united Ireland would have to be put to the people in a referendum, or border poll. In this episode of The Inquiry we ask, will there be a united Ireland?Presented by Gary O’Donoghue.(map / Getty images)

It’s a year since President Putin launched a full scale invasion of Ukraine. Russia currently holds areas in the South and East of Ukraine including Donetsk and Luhansk but the Ukrainian army, helped militarily by its allies, has regained control over key towns and large swathes of land. Russia is also thought to have lost 20,000 soldiers in the conflict.But it is reinforcing its ranks with hundreds of thousands of new conscripts, and experts suggest Russia may be positioning fighter jets and gathering troops on the border for a renewed land offensive. So we’re asking - What is Putin’s plan now for Ukraine?

The owner of Facebook - Meta - is reinstating Donald Trump’s account after a two-year suspension. The former US president was suspended from Facebook and Instagram after his posts were deemed to have encouraged the Capitol riots in 2021. In a statement Meta's president of global affairs, Nick Clegg, said a review found Mr Trump's accounts were no longer a risk to public safety. Donald Trump pointed out that Facebook was in financial trouble and probably needed him back for the money it can raise.Daily user numbers for Facebook grew to an average of two billion in December 2022 - about a quarter of the world's population. The bigger-than-expected growth helped drive new optimism about the company, which has been under pressure as its costs rise and advertising sales drop.Where does the social media giant go from here? Does it have a future and clear direction of travel? How did it become so big? How does it work now and what does it do with our data? Also, when has it gone wrong and what are its challenges now?This week on The Inquiry, we’re asking: is everything okay at Facebook?Presented by Charmaine CozierResearcher John Cossee Producer Simon Coe Editor Tara McDermott Technical producer Richard Hannaford Broadcast Coordinator Brenda Brown(Facebook symbol.

On 25 February, Nigerians go to the ballot box to vote for their next president. For the first time in a long time, the Incumbent president will not be contesting the elections – having already served the maximum allowed two terms.Since 2016, the country has spiralled down as inflation has hit over 20% and unemployment rides at around 30% overall, and 60% for the young. Banditry and kidnappings have become lucrative methods of making a living in the country and a pervading sense that this could be now or never for Nigerians hangs ominously.Three candidates have emerged as the front runners for the elections. The stalwarts Bola Ahmed Tinubu of the All Progressive Congress, or APC, and Atiku Abubakar, of the People’s Democratic Party, or DPD, are familiar faces from familiar parties. Power has been shared between the two parties since 1999.Peter Obi is the outsider who has taken a dramatic lead over recent weeks in the polls. He represents the Labour Party who have never held power and is offering to run the country in a different manner to what the country has been used to thus far.Foreshadowing the entire event is the expectation that Nigeria is expected to reach a population of around 400 million by 2050, making it the fourth largest country in terms of population by this date. That is an increase of around 60-80% of the current population estimates. Ensuring the infrastructure is in place for such a boom in population will be pivotal to Nigeria’s ability to both maximise the potential for its citizens whilst gaining the most from them.Presenter: Charmaine Cozier Producer: Christopher Blake Researcher: John Cossee Editor: Tara McDermott(Photo: Supporter of Nigerian opposition the Labour Party waves a green and white flag in a street procession in Ikeja district, Lagos, Nigeria.

Following the exit of US forces in 2021, the Taliban rolled back into power almost immediately. They promised that they had learnt from previous mistakes and did not want to minimalize the role of women. However, little over 18 months later and the Taliban have just announced that women were now banned from the universities and working for NGO’s, just the latest in a succession of repressive policies aimed at women.Furthermore, Afghanistan still has an insurgency problem. The Islamic State of Khorasan, or IS-K, formed in 2016 following disaffected Taliban members gaining inspiration from the gains maid by IS in both Iraq and Syria. They regard the Taliban as traitors and have their own desires that stretch far beyond the borders of Afghanistan.In the middle are Afghanistan’s citizens who find themselves victims from all sides. The Taliban’s focus on implementing Sharia law regardless of the impact has both all but erased women from society and left the economy in perilous state.Can the Taliban gain control of its own borders or does it need external help? And if so, does that offer a window to gain some leverage regarding human rights in the country? Find out as we ask, Can the Taliban tackle Afghanistan’s terror problem?

Since the start of the war, Ukraine has received more than €115 billion in military, financial and humanitarian aid from countries around the world. Now that the pendulum has swung, and the battlefield momentum is with Ukrainian forces, international allies have agreed to ramp up that support, with the US, UK and other major and minor military powers combining to pledge billions in weapons, ammunition and even modern tanks. But can that support go on indefinitely? As some countries run low on weapons stocks, will they cut off support to Ukraine rather than leave their borders vulnerable to potential attack? And will other factors such as rising energy costs, a looming global recession and the upcoming US presidential election determine to what extent - and for how long - international allies can fund Ukraine’s war effort?Image: Ukrainian soldiers practice with a mortar on the Donbass frontline on 19 January, 2023 (Credit: Diego Herrera Carcedo/Anadolu Agency via Getty Images)

The world is becoming increasingly dependent on advanced microchips to power its high-end technology, However, they are made by just one company in Taiwan, TSMC, meaning the rest of the world is largely reliant on the country to produce its microchips. This is no accident and is in fact by Taiwanese design. Over three decades ago Taiwan decided to focus its resources on becoming the most advanced producer of microchips. Not only has this been of great profit for Taiwan’s economy its helped with security too – offering the country protection from its neighbour China by creating what’s been described as the ‘Silicon shield’, in other words, the US is largely dependent on Taiwan to sustain its high-end tech. Given both the USA’s and EU’s recent announcements that they are now heavily investing in and subsidising their own microchip industries, the question becomes is this still sustainable?Presenter: Charmaine Cozier Producer: Christopher Blake and Ravi Naik Editor: Tara McDermott

A campaign called “ReBoot Food” was launched at the COP27 climate change conference in Egypt, to ask world governments to support a technology called precision fermentation. They claim it’s possible to produce enough food to feed the whole world in an area the size of London. The process uses genetically-engineered microbes to make cheap, high quality fats and proteins, virtually identical to those produced by animal farming. Its proponents say it will free up huge tracts of farmland and could even help reduce greenhouse gas emissions. A technology research group is even projecting the collapse of dairy and cattle industries by 2030 with animal meat being replaced by food grown using precision fermentation. But what is it, what are the potential pitfalls, and can the public stomach the idea of protein grown in an a bioreactor rather than on a farm? On this week’s Inquiry, we ask: can microbes feed the world?

Canada is just one of a number of countries with an ageing population and shrinking workforce. The second largest in the world in terms of land mass, and with a population of just 36 million, Canada has announced a plan to invite 1.5 million people to migrate there over the next three years. The ambitious target is not without challenge politically, the most prominent is the housing crisis currently being felt in the country.Canada is not alone in needing more people of working age to bolster its economy, developed nations all around the globe are finding themselves in a similar situation and struggling to find answers. Despite this need, many countries remain reluctant to embrace the notion of inviting larger numbers of immigrants in for a whole host of reasons, from a lack of space to negative media portrayals of migrants. None-the-less, gaps in their skilled trades’ sectors demand resolution, and increased immigration can offer it.Whilst increased migration can help a country like Canada overcome the challenges of a diminishing labour force, it also has the effect of denying a migrant’s home country of expertise. Not only can this have the effect of denying a country their brightest and best, it also comes with a financial cost too, with countries training more than they need in anticipation of losing a high percentage of those workers. So this week on the Inquiry we're asking, should other countries adopt Canada's immigration model?
