The UK and France have agreed to coordinate supplying weapons to Ukraine and training Ukrainian marines.
The leaders of both countries expressed their support for Ukraine during their summit and vowed to put Ukraine in the "strongest possible position" to negotiate a ceasefire with Russia.
Meanwhile, Hungarian Prime Minister Viktor Orbán criticised Ukraine's allies of promoting a conflict, which he saw as increasing the likelihood of it turning into a world war.
The UK and France held a summit to discuss ways of supporting Ukraine and staving off aggression from Russia.
During the summit, UK Prime Minister Rishi Sunak and French President Emmanuel Macron signed a declaration to provide training to Ukrainian marines and supply weapons to Ukraine, with the aim of strengthening Ukraine's position in negotiating a ceasefire with Russia.
The immediate priority is to bolster Ukrainian President Volodymyr Zelensky's forces and mount a successful counter-offensive.
The support was announced amid escalating violence in Ukraine, against which Viktor Orbán warned of a global conflict, claiming that the world has never been so close to local war turning into a world war.
Sunak, on the other hand, announced that reconciliation is a priority but assured that new support measures are aimed at putting Kyiv in the "strongest possible position" to negotiate a ceasefire.
Lastly, Orbán criticised Western capitals for promoting a conflict, while Sunak said their stance marks a clear divide from that of his predecessor Boris Johnson who urged the UK to send jets and tanks to help Ukraine "finish the job".
