Russian President Vladimir Putin has invited Ukraine to take part in “direct talks” on 15 May, hours after European leaders urged Moscow to agree to a 30-day ceasefire.

In a rare televised late-night address from the Kremlin, Putin said Russia was seeking “serious negotiations” aimed at “moving towards a lasting, strong peace”.

Earlier on Saturday, UK Prime Minister Sir Keir Starmer travelled to Kyiv with counterparts from France, Germany and Poland to put pressure on Russia to commit to an unconditional ceasefire, starting Monday.

Kremlin spokesman Dmitry Peskov later said Moscow would “have to think this through” – but warned that “trying to pressure us is quite useless”.

In his own statement, Putin said he could “not rule out” the possibility that the talks could result in Russia and Ukraine agreeing “a new truce”. But he did not address calls for a 30-day ceasefire directly.

The Russian leader said the proposed talks should be held in the Turkish city of Istanbul, as they have been before, and that he would speak to Turkey’s President Recep Tayyip Erdogan on Sunday to discuss the details.

Kyiv has not responded to the invitation.

The Ukrainian capital played host on Saturday to Sir Keir, France’s Emmanuel Macron, Germany’s Friedrich Merz and Poland’s Donald Tusk, who form part of the “coalition of the willing” – a group of countries committed to supporting Ukraine.

Alongside Ukrainian President Volodymyr Zelensky, they took part in a joint news conference.

The leaders warned that “new and massive” sanctions would be imposed on Russia’s energy and banking sectors should Putin not agree to the unconditional 30-day ceasefire “in the air, at sea and on land”.

They also said they had discussed the proposal with Donald Trump. Sir Keir later told the BBC the US president was “absolutely clear” that their suggestion of an immediate ceasefire was a “demand that must be met”.

After the meeting, Zelensky thanked the assembled leaders for “standing with” Ukraine.

“Today we will focus on how to build and guarantee real and lasting security,” he said.

Responding to the proposal, the Kremlin’s Peskov said: “It is a new development. But trying to pressure us is quite useless.”

Russian state media also quoted him as saying that statements from Europe were “generally confrontational in nature rather than aimed at trying to revive our relations”.

Moscow has previously said that before considering a ceasefire, the West must first halt its military aid to Ukraine.

Putin later made his own statement, with video showing journalists assembled in a hall inside the Kremlin.

“This would be the first step towards a long-term, lasting peace, rather than a prologue to more armed hostilities after the Ukrainian armed forces get new armaments and personnel, after feverish trench-digging and the establishment of new command posts,” he said.

“Who needs peace like that?”

Trump described Putin’s announcement as a “potentially great day for Russia and Ukraine”, in a post on Truth Social.

“It will be a whole new, and much better world,” he said, adding that he would “continue to work with both sides to make sure that it happens”.

Meanwhile, Putin also accused Ukraine of having repeatedly failed to respond to multiple ceasefire proposals from Moscow, including a 30-day halt in attacks on energy infrastructure and last month’s Easter truce.

Another ceasefire Putin flagged was one he ordered in April to coincide with World War Two commemorations. It ended on Saturday at midnight local time (21:00 GMT).

Kyiv had rejected the unilateral, three-day ceasefire, calling it a “theatrical show”. Instead, Zelensky reiterated calls for a longer truce of at least 30 days.

While it saw a decrease in fighting, each side accused the other of breaches.

On Thursday – the same day the supposed ceasefire took effect – Ukraine accused Russia of more than 730 violations and said it was responding “appropriately”.

Russia’s defence ministry insisted the truce was being observed, before accusing Ukraine of 488 violations.

“In spite of everything, we are offering the Kyiv authorities to resume the negotiations… resume direct talks, and I stress, without any preconditions,” Putin said on Saturday.

The last direct talks between Moscow and Kyiv took place in 2022, the year Russia launched its full-scale invasion of Ukraine.
