UK defence secretary’s remarks come as Western countries promise $1.55bn more in military aid to Kyiv.

The British defence secretary has said Russia is unlikely to succeed in occupying Ukraine as Western nations pledged 1.5bn euros ($1.55bn) more to help boost the Ukrainian military in its fight against Russia.

Ben Wallace said Russia’s invasion had “faltered” and was “starting to fail” as 26 countries agreed to give more financial and military aid to Ukraine at a conference in Copenhagen on Thursday, co-hosted by Wallace and the Danish defence minister Morten Bodskov.

Wallace said it was important to understand that fighting and loss of life were still taking place, but added Russia was “starting to fail in many areas”.

“Their invasion has … constantly been remodified to the extent they are really only focusing in parts of the south and in the east, a long, long way away from their three-day so-called special operation,” he said.

Wallace hailed the meeting in Copenhagen saying that the pledges made were “all designed to help Ukraine win, to help Ukraine stand up for its sovereignty and indeed to ensure that President Putin’s ambitions fail in Ukraine, as they rightly should”.

The commitments come after the government in Kyiv made repeated appeals to the West to send more weapons, including long-range artillery, as it tries to turn the tide on Russia’s February 24 invasion.

Ukrainian defence minister Oleksii Reznikov, who was also present at the meeting, thanked European allies for being “reliable partners”.

He wrote in a tweet, “Increased gas and fuel prices in the West are small prices for peace. Ukrainians pay for the peace in the rest of Europe with their lives. We must prevail over the killer state and de-occupy our territories, including Crimea. For me, everything impossible is possible, it just takes time.”

Ukraine said earlier this month that it had received another delivery of high-precision heavy weapons from Germany and the United States.

Moscow, which has accused the West of dragging out the conflict by giving Ukraine more arms, says it is conducting a “special military operation” in Ukraine aimed at safeguarding Russia’s security against NATO expansion.

Ukraine and its allies accuse Russia of launching an imperial-style war of aggression.

Defence ministers of Poland, Slovakia and the Czech Republic signalled a willingness to expand the production of artillery systems, munitions, and other military equipment to Ukraine, Bodskov said.

The United Kingdom, which has already donated advanced weapons systems to Ukraine and given thousands of its troop’s military training, on Thursday pledged an additional 300 million euros ($309 million), including multiple-launch rocket systems and precision-guided M31A1 missiles that can hit targets up to 80km (50 miles) away.
