Sir Keir Starmer's relationship with the civil service has broken down following the sacking of Sir Olly Robbins.

The former top civil servant at the Foreign Office told parliament there was a "dismissive approach" to security vetting from No 10, but the prime minister maintains it was Robbins who made "an error of judgement".

So, what's at stake when the inner workings of government grind to a halt?

Lord Peter Ricketts, who is also a former permanent secretary at the Foreign Office, joins Niall to discuss what happens when things go wrong and whether Starmer can repair relations with the civil servants who deliver his mandate, before it's too late.

First it was Venezuela, then Iran. Is Cuba next on Donald Trump's hit list?

The US navy has been anchored off the Caribbean coast since the start of the year, preventing supplies of oil and food from the outside world.

As a consequence, the island has been brought to its knees - with electrical blackouts, food rationing and fears for the future.

Sky News chief correspondent Stuart Ramsay joins Niall to discuss life under the blockade in Havana and what fate awaits the nation, as President Trump threatens military intervention.

Top civil servant Olly Robbins has been sacked after his department did not inform the prime minister that Lord Mandelson had failed security vetting for the role of US ambassador.

Opposition parties are calling on the prime minister to resign but Sir Keir Starmer is insisting he wasn’t told, in an "unforgivable" omission.

He's due to speak to MPs in parliament on Monday, and address the accusations he misled them over the process of Mandelson’s appointment.

But who is Olly Robbins, the man who has lost his job over the latest Mandelson revelation and is he being used as a fall guy? And how toxic will the row be for Sir Keir?

A multi-billion-dollar Saudi-backed golf tour is reportedly close to collapse – so could this spell an end to the Gulf state’s interest in sport?

The controversial LIV Golf Tour is just one strand of the Saudis’ sporting portfolio.

Footballing superstar Cristiano Ronaldo plays there, while the country’s Public Investment Fund (PIF) also owns English Premier League team, Newcastle United.

But the PIF - which has plunged $5b into the LIV project - has a new five-year economic strategy that includes no mention of sport. Having been accused of using sport as a political tool to legitimise the Saudi regime, what led to this apparent change of strategy?

Sky News’ sports correspondent Rob Harris joins Niall to discuss what it means for the future of Saudi sport.

Another night, another post on Truth Social from Donald Trump criticising NATO. As other leaders try to persuade him to stay in the alliance, plans are being prepared in case the US goes through with its threat to walk away.

Niall and Sky's military analyst Professor Michael Clarke debrief on what a post-Trump NATO might look like.

A decade on, you might have thought Brexit was done and dusted – but our relationship with the European Union is still in flux.

Prime Minister Sir Keir Starmer is proposing a reset that could result in the UK signing up to EU rules without the need for a normal parliamentary vote, under what are known as Henry VIII powers.

But in pushing for closer ties with the continent, is he risking a return to rule-taking without any say in what those rules are? And what might this new relationship with Brussels look like?

Niall speaks to Professor Anand Menon, director at UK in a Changing Europe, about the significance of this moment in UK-EU relations.

After 16 years in power, Hungary's Viktor Orban has been defeated by Peter Magyar, whose Tisza party has won a huge parliamentary majority.

Magyar campaigned to break the country away from Russia's grip and re-establish closer ties to the European Union, in a setback for both Vladimir Putin and Donald Trump. But is this a genuine turning point and a strategic win for Ukraine's war efforts?

Niall speaks to our Moscow correspondent Ivor Bennett in Budapest to find out how significant the change of regime could be across the continent.

Donald Trump's war in Iran has been polling badly among many of the groups that voted for him in 2024, and that matters as crucial midterm elections are just over six months away.

These elections take place two years into the presidential cycle, with voters able to choose who runs Congress. Currently, the Republicans control both the Senate and the House of Representatives, giving the president freedom to enact his agenda.

So how exactly do the midterms work and how much would change for Donald Trump if his Republican party has a bad night?

Niall is joined by US correspondent and co-host of the Trump100 podcast, James Matthews.
