Breaking: President Trump said Sunday night that Ukraine can end the war “almost immediately” as he anticipates the arrival of President Zelenskyy and a delegation of powerful European presidents, prime ministers and leaders…

Donald Trump supports Vladimir Putin’s demand that Ukraine surrender its most valuable region to Russia in order to end the war.

The Russian leader wants full control of Donetsk, the mineral-rich eastern oblast, including parts that are currently held by Ukraine within the wider Donbas region.

In return, Putin said he would freeze the front line and promised not to take any more territory.

Putin relayed his demands at a high-stakes meeting in Alaska with Mr Trump, who will meet Volodymyr Zelensky, the Ukrainian president, in Washington on Monday to discuss the offer.

A source with knowledge of the matter said Putin “de facto demands that Ukraine leave Donbas”, which consists of the Donetsk and Luhansk regions in eastern Ukraine. “Trump is inclined to support it,” the source said.

In return, the United States president has offered security guarantees to Ukraine if a peace deal is secured. As with Nato’s Article 5 mutual defence clause, such guarantees would mean the US and Ukraine’s European allies would be obliged to respond to a future Russian attack.

While the proposed protections stop short of making Ukraine a Nato member, it marks the first time Mr Trump has indicated he would join the Coalition of the Willing, led by Britain, France and Germany.

A Republican source close to Mr Trump told The Telegraph: “The president wants to stop the killing and end the war. That’s the bottom line. Negotiations over territory are part of that process. The ball is in Zelensky’s court.”

Sir Keir Starmer and other coalition leaders will meet on Sunday ahead of the Washington summit.

European leaders are understood to be concerned that Mr Zelensky will reject any offer that involves ceding land and provoke an angry reaction from Mr Trump, with whom he clashed in the Oval Office earlier this year.

“Trump wants this done as soon as possible and I don’t think it will take long,” a European official said.

It remains likely that Ukraine will reject Putin’s terms. Mr Zelensky has made clear that he is not willing to discuss ceding Ukrainian territory, and European governments have said that any decisions surrounding exchanges of land should be made by Kyiv alone.

A diplomatic source said: “Germany, France and the UK are preparing for Monday’s talks, including how best to support Zelensky and how not to push Trump into a corner.”

Another added: “The worst thing for all will be if the visit causes a public reaction from President Trump that we can’t walk back from.”
