UK Prime Minister Sir Keir Starmer has reaffirmed his dedication to Ukraine's sovereignty during a phone call with Ukrainian President Volodymyr Zelensky on Saturday.

This conversation was their second in a span of four days, following recent events related to US President Donald Trump's efforts to enhance ties with Russia amid the ongoing conflict in Ukraine.

Starmer highlighted the UK's 'ironclad support' for Ukraine, stressing the importance of involving Ukrainian voices in any peace talks aimed at resolving the crisis.

During the call, Starmer stated that 'Ukraine must be at the center of any negotiations to conclude the war' and reiterated the UK's commitment to fostering a 'just and lasting peace' in response to Russia's actions.

He emphasized that protecting Ukraine's sovereignty is vital for deterring future Russian aggression.

Starmer mentioned that he will further address these critical matters during his upcoming visit to Washington D.C. to meet with Trump.

Zelensky described the conversation as fruitful, expressing gratitude for the continuing military collaboration and joint strategic planning between Ukraine and the UK. He noted that the coming week would be notably active in terms of partnerships.

In related comments published in The Sun, Starmer acknowledged Trump's view that European countries need to take more responsibility for their security and increase defense spending, advocating for action on these fronts.

He reiterated that Ukraine should play an essential role in any negotiations and stressed the necessity for strong security guarantees, suggesting the involvement of the United States in that commitment.

In a separate conversation, Starmer also spoke with European Commission President Ursula von der Leyen, agreeing on the need for Europe to 'step up for the good of collective European security.'

Starmer's upcoming talks with Trump occur amidst a series of significant diplomatic discussions among European leaders attempting to navigate the evolving dynamics of US-Russia relations following Trump's initiatives.

Last week, European leaders gathered for an urgent summit in Paris to address worries about the possible exclusion of Ukraine and Europe from future peace discussions.

Trump's recent remarks, which included labeling Zelensky a 'dictator' and minimizing the Ukrainian president's role in negotiations, have elicited reactions from European officials and advocacy organizations.

At the same time, public demonstrations took place in London, where around 2,000 protesters marched from the Ukrainian embassy to the Russian embassy to commemorate the third anniversary of Russia's full-scale invasion.

Protesters, advocating for solidarity with Ukraine and a more aggressive stance against Russia, included MPs and activists expressing critical opinions on Trump's engagement strategy.

Participants underscored the necessity of prioritizing Ukraine's interests in any diplomatic talks concerning peace in the region.

Amid the protests, notable figures voiced their concerns regarding the consequences of Trump's strategy towards Russia and the potential impacts on Ukraine's future.

Demonstrators held signs championing Ukraine's sovereignty and rights, reflecting the broader public sentiment surrounding the ongoing conflict.
