Volodymyr Zelenskyy has given a wide-ranging interview to Sky News in which he was asked about the prospect of Russia attacking NATO, whether he would cede land as part of a peace deal and how to force Vladimir Putin to the negotiating table.
The Ukrainian president spoke to chief presenter Mark Austin.
Here are the five key takeaways from their discussion.
NATO ‘at risk of attack’
Mr Zelenskyy said plans for NATO members to increase defence spending to 5% of GDP by 2035 are “very slow” and warned Russia could attack a NATO country within five years to test the alliance.
“We believe that, starting from 2030, Putin can have significantly greater capabilities,” he said. “Today, Ukraine is holding him up, he has no time to drill the army.”
But while Mr Zelenskyy conceded his ambition to join NATO “isn’t possible now”, he asserted long term “NATO needs Ukrainians”.
US support ‘may be reduced’
Asked about his views on the Israel-Iran conflict, and the impact of a wider Middle East war on Ukraine, Mr Zelenskyy accepted the “political focus is changing”.
“This means that aid from partners, above all from the United States, may be reduced,” he said.
“He [Putin] will increase strikes against us to use this opportunity, to use the fact that America’s focus is changing over to the Middle East.”
On the subject of Mr Putin’s close relationship with Iran, which has supplied Russia with attack drones, Mr Zelenskyy said: “The Russians will feel the advantage on the battlefield and it will be difficult for us.”

Trump and Putin ‘will never be friends’
Mr Zelenskyy was sceptical about Mr Putin’s relationship with Donald Trump.
“I truly don’t know what relationship Trump has with Putin… but I am confident that President Trump understands that Ukrainians are allies to America, and the real existential enemy of America is Russia.
“They may be short-term partners, but they will never be friends.”
On his relationship with Mr Trump, Mr Zelenskyy was asked about whether he felt bullied by the US president during their spat in the Oval Office.

“I believe I conducted myself honestly. I really wanted America to be a strong partner… and to be honest, I was counting on that,” he said.
In a sign of potential frustration, the Ukrainian president added: “Indeed, there were things that don’t bring us closer to ending the war. There were some media… standing around us… talking about some small things like my suit. It’s not the main thing.”

Putin and peace talks
Mr Zelenskyy was clear he supported both a ceasefire and peace talks, adding that he would enter negotiations to understand “if real compromises are possible and if there is a real way to end the war”.
But he avoided directly saying whether he would be willing to surrender four annexed regions of Ukraine, as part of any peace deal.
“I don’t believe that he [Putin] is interested in these four regions. He wants to occupy Ukraine. Putin wants more,” he said.
“Putin is counting on a slow occupation of Ukraine, the reduction in European support and America standing back from this war completely… plus the removal of sanctions.
“But I think the strategy should be as follows: Pressure on Putin with political sanctions, with long-range weapons… to force him to the negotiating table.”

Russia ‘using UK tech for missiles’
On Monday, Mr Zelenskyy met Sir Keir Starmer and agreed to share battlefield technology, boosting Ukraine’s drone production, which Mr Zelenskyy described as a “strong step forward”.
But he also spoke about the failure to limit Russia’s access to crucial technology being used in military hardware.
He said “components for missiles and drones” from countries “including the UK” were being used by Russian companies who were not subject to sanctions.
“It is vitally important for us, and we’re handing these lists [of Russian companies] over to our partners and asking them to apply sanctions. Otherwise, the Russians will have missiles,” he added.
