Sir Keir Starmer is expected to urge partner nations to provide Ukraine with additional long-range missiles to target Moscow's positions during discussions in the UK capital on Friday.
The prime minister plans to receive Ukrainian President Volodymyr Zelensky alongside what's known as "coalition of the willing", including more than 20 of Kyiv's partners who have pledged to provide Ukraine protection commitments once a ceasefire is brokered.
Ukraine's president has been pleading for several weeks for additional advanced missile technology from allied countries, a step that the Russian government has cautions would worsen the conflict.
The Ukrainian president is travelling from Brussels, where he conferred with EU leaders on yesterday seeking funding aid.
"The sole individual engaged in current hostilities who declines to halt the war is Vladimir Putin," Sir Keir stated.
The Prime Minister will also reveal that one hundred extra air defense systems will be delivered to Ukrainian forces earlier than planned, as detailed in a substantial financial arrangement struck between the United Kingdom and the Ukrainian government in spring.
The Ukrainian president arrives off the back of significant diplomatic successes in recent days: Donald Trump's decision to enact new measures against Russia, and the European Union agreeing to fund Ukraine's financial gap.
Britain's leader is hoping to maintain the momentum by intensifying the leverage on Moscow to pursue an end to the war.
Britain's leader will encourage leaders to expand the supply of extended-range systems following a successful attack on a chemical plant in the Bryansk region, the Russian Federation, using UK-provided missile systems.
"Additionally, his brutal strikes on small children in a preschool recently demonstrate that crystal clear," he added.
Two children were included in at least seven lost in numerous enemy assaults on Ukraine, which targeted a preschool facility in the major urban center the eastern city.
Britain's leader will discuss with supporting countries on methods to take Moscow's energy exports from international trade.
They will furthermore discuss utilizing frozen Russian assets to supply Kyiv with financial loans, while the initiative encountered insufficient agreement and regulatory obstacles at the Brussels summit on Thursday.
European Union declined to approving a plan to employ approximately €140 billion in seized Russian resources to economically support Ukraine.
However, the delegates agreed to help support Ukraine's "economic requirements" for the next two years.
America additionally disclosed measures on midweek against Russia's biggest petroleum firms, Rosneft Oil and Lukoil Corporation, as part of efforts to increase economic pressure on Russia to commence ceasefire negotiations.
Moscow launched its comprehensive attack of Ukrainian territory in winter 2022. It currently holds about one-fifth of Ukrainian territory, comprising the Crimean peninsula Russia annexed in 2014.
