During a meeting on August 18 at the White House, British Prime Minister Keir Starmer’s representative highlighted the importance of U.S. proposals regarding security guarantees for Ukraine, calling it a "significant positive step", while noting that many details still need to be discussed.

According to a publication by BBC, Monday's talks mark a "key step towards lasting peace". The spokesperson stated that Ukraine requires "solid" security guarantees.

He pointed out that the details will be subject to discussion, but the "coalition of the determined" is actively preparing to ensure security following the end of hostilities, as well as to assist Ukraine in protecting its air and maritime space and rebuilding its armed forces. "We will certainly continue discussions with the United States", he emphasized.

When asked about the possibility of exchanging occupied territories, the spokesperson stressed that the issue of Ukraine's borders should be resolved through negotiations, and that international borders cannot be changed by force.

He also reiterated that the UK's position on Ukraine's NATO membership remains unchanged, despite Donald Trump's statements suggesting that Ukraine should not join the Alliance.

Starmer’s representative also emphasized that "Russia should not have a veto over Ukraine's path to Europe".

Recently, Trump administration officials - Secretary of State Marco Rubio and Special Envoy Steve Witkoff - stated that at the meeting in Alaska on August 15, Putin acknowledged for the first time that the U.S. and European allies could provide security guarantees to Ukraine to deter further Russian aggression. One of Trump’s advisors suggested that the U.S. could deploy its troops in Ukraine as part of potential security guarantees following the cessation of hostilities. President Volodymyr Zelensky stated on Sunday that he does not have detailed information about the guarantees discussed by Trump and Putin in Alaska, but he noted it as a "significant signal" from the U.S. President.
