This is the last time Antonio Guterres will open the UN General Debate with his speech as secretary general. His term ends on 31 December and a number of candidates to replace him are here this week trying to network and lobby delegates for the job.

Guterres’s critics argue that he focused on existential threats such as climate change and AI far more than on the core mission of the organization - conflict resolution.

His supporters argue he navigated the UN through several years of two Trump administrations, the Covid pandemic and major wars while limiting the fallout.

Ahead of the UNGA, Guterres declined to discuss his legacy, only sharing that he believes the UN has achieved more gender parity under his term.

He said if anyone needs to offer a “mea culpa” to the world though, it’s the leaders who have failed to find consensus, including the divided and paralysed UN Security Council which holds real power to authorise sanctions or military action.

His address to world leaders today will argue that all of the problems facing society boil down to power - who has it and who is denied it. He will ask those gathered in the hall if they will act to ensure power is governed by law or by force, by cooperation or coercion.

Zelensky seeks fresh answers to familiar problems for Ukrainepublished at 13:38 BST

As President Zelensky prepares to meet President Trump in New York later today - and as explosions are once again audible here in Kyiv - his wish list is a familiar one. “We…raised our need for ballistic missile interceptors and the challenges we face ahead of the coming winter,” Zelensky posted on X after meeting US senators.

The approaching winter is looming large in everyone’s minds. Last winter was the toughest so far and Ukraine wants to garner as much practical support as it can to get through the next. With American-made Patriot missile interceptors in short supply, the president is looking for other solutions.

Earlier, he said he was willing to use EU loan money to purchase French-made SAMP/T air defence equipment, and thanked France’s Emanuel Macron for his support for a joint European Ukrainian anti-ballistic missile programme known as Freyja.

Zelensky will also be hoping that Trump will indicate a willingness to use his powers under the Sanctioning Russia Act - passed by the House earlier this month and signed by the president four days ago – to put more economic pressure on Russia and countries that continue to buy its energy products.

In just over half an hour, the UN secretary general will open this year’s General Debate of the 81st UN General Assembly, presenting his annual report on the work of the organisation.

This will be the last time Antonio Guterres will address the annual gathering of world leaders as UN chief. He is due to step down at the end of the year and the selection process for the next secretary general is under way.

Expect him to touch upon conflicts in Iran and the wider Middle East and also one of his signature projects - the threats posed by AI.

UN Secretary General Antonio Guterres will deliver his annual report on the first day of this year's General Assembly, before the assembly's President Khalilur Rahman formally opens debate.

There will be two sessions, with the first running from 09:00 to 14:45 ET (14:00 BST to 19:45 BST).

Brazilian President Luiz Inácio Lula da Silva will kick off the first session, followed by a speech from US President Donald Trump.

We will also hear from King Abdullah II of Jordan, Turkish President Recep Tayyip Erdoğan, and the French President Emmanuel Macron.

The afternoon session will be held from 15:00 to 21:00 ET (20:00 BST to 02:00 BST), starting with the president of Mongolia Ukhnaagiin Khürelsükh and South Korea's President Lee Jae Myung.

Andy Burnham has woken here in New York to the prospect of this being one of those talking-to-the-archive days. Moments on camera with the potential to be replayed on the loop of his emerging prime ministerial story.

There is the key first face-to-face encounter with President Trump in a few hours’ time. You don’t need to be steeped in political minutiae to spot the potential peril lurking for him there.

Later, a meeting’s expected with Ursula Von Der Leyen of the European Commission.

He will urge her not to use protectionist measures designed to counter China to freeze UK firms out of European contracts.

The prime minister has reflected that Brexit not only created “turbulence” as he put it, but claims “outside actors” sought “to manipulate, to distort facts” and “influence the democratic process” and the UK must be more “clear eyed” about these threats in the future.

UK Prime Minister Andy Burnham will have his first face-to-face meeting with Donald Trump at the United Nations in New York later today.

Burnham has travelled to the US with his wife, Marie-France van Heel, for a day of diplomacy and a speech to the UN General Assembly, which is expected to focus on the opportunities and dangers associated with artificial intelligence.

The prime minister told reporters on his flight that he expects to find "common ground" with the president, and he believes the relationship between the UK and US is "as strong as it's ever been".

The two men have spoken by phone twice since Burnham became prime minister in July, with Downing Street saying those calls established a "productive relationship".

The United Nations is an international organisation which was formed after the end of World War Two with the aim of maintaining international peace.

The UN General Assembly is the organisation’s main meeting, during which member states discuss a range of international issues.

It is the only meeting at which all of the 193 UN members are represented and takes place every September at the UN's headquarters in New York.

The gathering also sees the appointment of the new secretary-general on the recommendation of the Security Council, as well as the election of the non-permanent members of that all-important body.

The UN’s budget will also be approved. Part of the meeting includes the general debate, during which representatives from every country in the UN can speak, to raise matters which concern them.

It’s early morning in New York City, where US President Donald Trump has a packed schedule ahead of him.

In a short while, the president will leave Trump Tower to head to the UN, where he is scheduled to deliver remarks at 09:55 ET/14:45 BST.

Administration officials have signalled that much of his speech will focus on what, in his opinion, the US has done to confront challenges around the world, including Iran’s nuclear programme.

Additionally, he is also likely to reiterate long-standing grievances against the UN and some of its member states over topics ranging from climate change to migration, and markets will be watching for any commentary on energy supplies or AI.

Following the speech, Trump has a long series of back-to-back meetings and events, including an event to sign a deal over Greenland, meetings with the UK and Japan’s prime Ministers, Ukraine’s Volodymyr Zelensky and Gulf leaders.

Notably, some of these events will take place without TV crews from the White House press pool which have pulled out of coverage in solidarity with CNN, which Trump has banned from the White House along with Politico and MSNOW.
