Bird-flu, bombs and asteroids: are we heading for disaster in 2026? What are the biggest threats to global health security in 2026? Is it bird flu? Or the rising threat posed by nuclear weapons? Could we even be hit by an asteroid?

Dr Becky Alexis-Martin, a Lecturer in Peace Studies at the University of Bradford and an expert on nuclear weapons, argues that the threat they pose will continue to rise in the new year.

Paul Nuki, the Telegraph’s Global Health Security Editor, warns that numerous diseases linked to conflict are likely to continue to spread in 2026 – in particular cholera and HIV.

Meanwhile, the possibility of H5N1 bird flu making the jump to humans and causing a pandemic remains a primary threat, as does the continued spread of mpox around the world.

Lord Martin Rees, the former Astronomer Royal and a founder of the Centre for the Study of Existential Risk, assesses the risk of space-based threats.

This episode goes straight to the jugular of modern air power and asks a brutally simple question: has the last great manned fighter already been born?

Roland is joined by Tom Withington of Royal United Services Institute and Sophy Antrobus from King’s College London, two people who actually know what they’re talking about when it comes to fighter jets. They unpack the mystery and the hype surrounding the sixth generation fighters. These are not just faster jets with shinier wings. They are flying data centres, designed to hoover up information, evade the most lethal air defences on the planet, and command swarms of drones doing the truly dangerous work.

We cut through the fog of acronyms to explain what sixth generation really means, how it differs from the F-35, and why programmes in the US, Britain, Europe and Asia are racing ahead despite eye watering costs. This is air dominance, power politics and future war rolled into one.

This has been a year when the world lurched from crisis to crisis at breakneck speed. Trump back in power. America wavering on Europe and Ukraine. China strutting with new confidence. Russia grinding on. Iran bombed. Gaza paused. If you feel dizzy you are not alone.

Venetia is joined by Adelie Pojzman-Pontay from Ukraine the Latest and Asia correspondent Allegra Mendelson to take a sharp eyed look back at the moments that mattered and the ones you may have missed but cannot afford to ignore.

We focus on the three powers shaping everything China, Russia and the United States.

Former UK ambassador Laurie Bristow speaks to Roland and delivers a blunt and unsettling warning about the state of the world and Britain’s place in it. Drawing on more than three decades at the heart of the Foreign Office, including some of the most dangerous postings of modern times, he argues we are living through the most volatile and complex global moment of our lifetimes.

From war returning to Europe and the rise of China, to artificial intelligence, pandemics and the collapse of old assumptions about power, nothing is stable and nothing is simple. Speaking candidly about Vladimir Putin, he explains why the west misread Moscow for years and why there are no easy deals or quick endings ahead.

This is a forensic, unsparing account of a world in turmoil and a challenge to Britain to wake up before it is too late.

Have you ever been scammed? If you have, the chances are that it happened somewhere in Asia. Often overseen by Chinese criminal gangs, the places where these scams are happening have become hubs for people trafficking, drugs trade, and prostitution.

On today's episode, Venetia speaks to Global Health Security Correspondent Sarah Newey, who has visited Sin City in Laos, a scam centre hotspot. She tells us about what happens inside these compounds.

We also hear from political analyst and Myanmar adviser to Crisis Group, Richard Horsey about why power vacuums are creating the perfect conditions for these criminal activities.

Today, Britain’s MI6 chief delivered a chilling message: the frontline is now everywhere.

Look around the world and the evidence is overwhelming. From Ukraine to Gaza to Sudan, violence is spreading fast and growing more lethal by the month. New data from ACLED shows that Europe is now the most intense conflict zone on the planet - a fact that should shock anyone in the West still clinging to the idea that war happens elsewhere. Plus, with drone strikes now accounting for more than a quarter of all attacks worldwide, war is only a short flight away.

This is not a bad patch, this is a dangerous new era. And next year will be even bloodier still. The warning signs are screaming at us.

The Armed Conflict Location and Event Data organisation, known as ACLED, has been tracking all of this data and more. Venetia speaks to their CEO Clionadh Raleigh to find out more.
