The Inquiry gets beyond the headlines to explore the trends, forces and ideas shaping the world.

The Inquiry

In February, Polish Prime Minister Donald Tusk posted a social media video celebrating new figures from the International Monetary Fund suggesting that the average person in Poland now has slightly more spending power than the average person in Spain, the European Union’s fourth largest economy. 

It’s a symbolic milestone for a country that emerged from communism just over three decades ago and once struggled with hyperinflation and economic upheaval. In 2025, Poland’s economy also passed the trillion-dollar mark, putting it in an elite group of just 20 countries globally.

Investment from across the EU has helped drive growth. But can Poland keep its edge as labour shortages grow and the war in neighbouring Ukraine continues to shape the region? 

This week on The Inquiry, Tanya Beckett asks: Why is Poland’s economy booming?

Why is Poland’s economy booming?

Half a million people are in Spain without official permission. 

They come mainly from Colombia, Peru, Honduras, Paraguay, and Argentina. It’s thought that most outstay their work, student, or tourist visas. 

An amnesty to grant them legal status to remain and work is due to start within weeks.

It's a very different approach from most other countries in Europe that have been tightening controls on migration.

The prime minister has admitted “Some say we've gone too far, that we're going against the current”.

Opposition parties argue that this policy puts pressure on public services.

This week on The Inquiry, we’re asking: “How will Spain’s migrant amnesty work?”

How will Spain’s migrant amnesty work?

Control of critical minerals is becoming a source of geopolitical tension. They are essential to modern technology and industries around the world, and China currently dominates the mining and processing industry.

As demand grows, governments in the United States and elsewhere are looking at ways to reduce their reliance on Chinese supply chains. That means investing in new mines and processing facilities even though they are expensive and environmentally toxic. 

Ultimately, the US and EU have a goal of diversifying the control of these lucrative elements. 

This week on The Inquiry, Tanya Beckett explores whether the rest of the world can catch up with China in the race for rare earths.

Can the world catch China in the rare earths race?

The 2026 men’s football World Cup will be the biggest ever staged. For the first time, 48 teams will compete, playing more than 100 matches across North America.

But the expanded scale comes at a cost. Ticket prices are far higher than at the last World Cup in Qatar. With matches also spread across the US, Mexico and Canada, attending the tournament is becoming unaffordable for many global fans.

FIFA says higher revenues will be reinvested to grow the game worldwide and has released some lower-priced tickets for dedicated supporters, but some fan groups say this isn’t going far enough. 

This week on The Inquiry, we’re asking: Is the 2026 World Cup an own goal?

Chennai, São Paulo, Mexico City, Tehran, Cape Town - these cities have all faced the threat of a ‘Zero Day’, or, having no fresh water left in their taps. 

The UN says we’re entering a ‘water bankruptcy’ era, meaning our water ‘current accounts’ are running empty, while our ‘savings accounts’ - the long term stores of water deep underground - have been depleted, with some beyond repair. 

So how did we get here?

Bangladesh will hold a national election in February, after years of political turmoil and the ousting of long-time leader Sheikh Hasina. Her rule of more than a decade delivered strong economic growth but was also accompanied by tighter political control and repeated confrontations with protesters.

Sheikh Hasina’s party, the Awami League, has been banned. This has brought renewed focus on the Bangladesh Nationalist Party’s leader Tarique Rahman, who is the son of former prime minister Khaleda Zia, as well as several emerging challengers.

Following years of unrest, the vote is seen as a test of whether Bangladesh can move towards political stability.

This week on The Inquiry, we’re asking: What does the national election mean for the future of Bangladesh?

Boosting, swiping or the five finger discount - many countries around the world are seeing a rise in retail theft. 

From Japan to the UK, the USA to Germany, retailers are struggling to tackle shoplifting - but the factors fueling this trend are as varied as the people carrying out these crimes. Poverty, opportunism, thrill-seeking - and technology - are some of the factors experts say are to blame. 
 
But a more costly problem is the rise in organised crime, as gangs of thieves strategically target shops and steal to order, turn to online marketplaces to anonymously sell on stolen goods for big profits.

Charmaine Cozier reveals how the justice system and surveillance technology are being used to combat this rising crime wave, as The Inquiry asks what’s behind the rise in shoplifting?

What's behind the rise in shoplifting?

Iran has been shaken by protests on a scale not seen since its 1979 revolution. 

Demonstrations that began in the country’s capital over the state of the economy have spread to multiple cities, with wider calls for political change.

The government has called the demonstrations "riots" backed by the nation’s enemies.

Thousands have been killed.

For some, the scenes bring back memories of the uprising that toppled the monarchy more than four decades ago. 

Crown Prince Reza Pahlavi, the exiled son of Iran’s last monarch, has emerged as a figure that could challenge the existing order.

This week on The Inquiry, we’re asking ‘Is history repeating itself in Iran?’

Is history repeating itself in Iran?

In February 2026, the last remaining nuclear arms control treaty bilateral between Russia and the United States is set to expire. The aim of the New START agreement was to reduce and limit the number of strategic nuclear warheads, but once this treaty comes to an end it means there will no longer be rules on the cap of these nuclear weapons. The legal provisions in the treaty for a one-time five-year extension, were used in 2021. 

The multilateral Nuclear Non-Proliferation Treaty (NPT) is still in place, to which 190 countries are signatories. The general idea behind the NPT was for nuclear countries to reduce their stockpiles of nuclear weapons, with the goal of complete disarmament. Whilst those countries without nuclear weapons would commit to not pursuing them. In 1995 the members agreed to extend the treaty indefinitely, but it is not without its challenges. Four nuclear powers sit outside the NPT and there are rifts between the non-nuclear and nuclear states. 

So, on The Inquiry this week we’re asking, ‘Is nuclear disarmament set to self-destruct?’

Is nuclear disarmament set to self-destruct?

Kenya is facing rising public discontent over allegations of political corruption, economic stagnation and a shortage of good quality jobs, particularly for the country’s Gen Z. 

One of the government’s flagship responses is an ambitious push into digital outsourcing. It argues that call centres, coding work and other IT-enabled services can position the country as a global hub and generate a million new jobs within five years.

The model has worked before in countries such as India and the Philippines, but the global landscape is shifting. Advances in artificial intelligence are already transforming the very roles Kenya hopes to attract, raising questions about whether this strategy can deliver long-term employment at scale.

Tanya Beckett asks whether Kenya’s vision for digital outsourcing can provide stability and opportunity for the country.

This week on The Inquiry, we’re asking: Can Kenya answer the call for employment?
