“We will deliver in the days to come additional Aster missiles, new training programs and new Mirages,” the French leader said in a video posted by the Elysee Palace on the X social network.

He added that France, together with some other members of the coalition, will “confirm some additional initiatives.”

Additionally, Macron asserted that the “coalition of the willing” “will also need to support Ukraine’s energy resilience.”

The Russian side has repeatedly noted that flooding Kiev with arms merely prolongs the conflict.

The prime minister urged other nations to follow the US and impose sanctions, and said allies had agreed on a “clear plan for the rest of the year” in supporting Kyiv.

Among the further pledges were plans to “push on with the progress” on Russian assets and “keep up the military pressure on Putin” as the conflict heads towards its fourth winter. The UK also announced it would “accelerate” its missile production programme to get more weapons to Ukraine.

It comes days after the White House imposed new sanctions on Russian oil in an attempt to squeeze Moscow.

Speaking in London after a coalition of the willing meeting alongside Zelensky, Sir Keir said: “We will act to take Russian oil and gas off the global market.

“Last week, the UK became the first country to sanction all of Russia’s oil majors. On Wednesday, the US acted decisively to join us together with further sanctions from the EU, and we’re choking off funding for Russia’s war machine.”

“I’m urging others to take these steps too, to go further to reduce their dependencies and incentivise third countries to stop buying these tainted resources,” he added.

The British and Ukrainian leaders were joined by NATO secretary general Mark Rutte, Dutch prime minister Dick Schoof and Danish prime minister Mette Frederiksen for a press conference at the Foreign Office in Westminster following their discussions.

Rutte described President Vladimir Putin’s refusal to engage in ceasefire talks as “deluded aggression” and said that “the truth is that Putin is running out of money, troops and ideas”.

The leaders in London were joined by others virtually. Zelensky stated that the group discussed “enhancing our air defence”.

In a post on social media on Friday afternoon, the Ukrainian leader stressed he is “grateful for the shared position on the need to further increase pressure on Russia and continue work with the United States on developing clear and reliable security guarantees for Ukraine”.

Sir Keir also added that the UK was “accelerating” the push to provide Kyiv with “more than 5,000 lightweight multirole missiles”. He told the press conference that the project is “creating 200 jobs and supporting 700 existing roles at Thales in Belfast”.

It comes amid a diplomacy push over the US providing Tomahawk missiles. Mr Rutte said the matter remains under “review”.

Earlier on Friday, Zelensky got a ceremonial welcome at Windsor Castle before a meeting with King Charles.

There was a royal salute as the Ukrainian leader shook hands with the King in the castle’s royal quadrangle – the first ceremonial welcome he has received in the UK.

Zelensky inspected the 1st Battalion of the Grenadier Guards and was then led inside the castle for an audience with the King.

The Ukrainian president told the press conference later that Russia “want to break Ukraine. They are doing everything to achieve it.”

While Zelensky continued to push for more military support from Europe, the Russian defence ministry said on Friday its forces had taken control of three more villages in eastern Ukraine.

According to the ministry, Russian troops have taken Bolohivka in the Kharkiv region, Promin in the Donetsk region, as well as Zlagoda in the Dnipropetrovsk region.

Earlier, the ministry also announced its forces had captured the settlement of Dronivka in the Donetsk region.

The reported gains come after Donald Trump ramped up pressure on Vladimir Putin with new sanctions on Russian oil.

The United States this week imposed sanctions on Russia’s largest oil companies, Lukoil and Rosneft, while EU countries approved their 19th package of sanctions on Moscow that included a ban on Russian liquefied natural gas imports.

Speaking to journalists after a meeting in Moscow, Putin cautioned that any use of Tomahawk missiles against Russian territory would provoke a powerful reaction. “This is an attempt at escalation,” he said.

“But if such weapons are used to strike Russian territory, the response will be very serious, if not downright staggering. Let them think about that.”

Ukrainian leader Volodymyr Zelensky reportedly raised the issue of obtaining Tomahawk missiles during his meeting with US President Donald Trump at the White House last week. According to Axios, the request was turned down, although US officials have stated that the option remains under review, with Trump expected to make the final decision.

The Tomahawk, a long-range cruise missile with a maximum range of around 2,500 kilometers (1,550 miles), requires lengthy and complex training to operate, Trump told reporters on Wednesday during talks with NATO Secretary-General Mark Rutte at the White House.

“This would be an escalation. It is an escalation attempt,” Putin stressed, commenting on a potential delivery.

“If Russian territory is hit… with such a weapon, the response will be very serious if not outright overwhelming,” the president added, encouraging Western leaders “to think about it.”

Moscow has previously warned that although Tomahawk deliveries would not affect the state of the battlefield of the Ukraine conflict, they would diminish peace prospects and strike a blow to US-Russian relations.

Putin discussed the issue with Trump during a phone call last week. Delivering the missiles would “severely undermine the prospects of a peaceful settlement,” he noted at the time. Following the call, Trump said it would be “not easy” for the US to provide Kiev with Tomahawks and maintained that Washington should not deplete its own arsenal for Ukraine.
