London Summit: Macron, Starmer, and Merz to Meet Zelensky on December 8, 2025, to Discuss Security Guarantees for Ukraine

On Monday, December 8, 2025, London is set to host a crucial meeting involving the President of Ukraine, Volodymyr Zelensky, alongside several prominent European leaders. Attendees will include French President Emmanuel Macron, UK Prime Minister Keir Starmer, and German Federal Chancellor Friedrich Merz. This high-level gathering underscores the urgency of the security situation facing Kyiv.

The central focus of the agenda will be a thorough evaluation of the ongoing peace process, which is currently being managed by American envoys, specifically mentioning Steve Witkoff and Jared Kushner. A major emphasis will be placed on establishing robust, long-term security guarantees for Ukraine. President Macron has reiterated his firm stance, asserting that achieving a lasting peace is unattainable without concerted efforts alongside Washington to secure these guarantees, given that the security of the entire European continent hangs in the balance.

This significant meeting follows a series of ongoing consultations mediated by the United States, with previous rounds having taken place in both Geneva and Miami. German Chancellor Merz, who assumed office in May 2025 after his election victory for the CDU party, intends to use this opportunity to showcase a unified European front concerning the crisis. Meanwhile, Prime Minister Starmer, leading the UK government since July 2024, will confirm continued British support for Ukraine. The UK has previously advocated within the OSCE for the establishment of reliable security mechanisms for Kyiv.

The summit arrives on the heels of a recent flare-up in tensions. In the early hours of Saturday, December 6, 2025, Russia launched a large-scale assault targeting Ukraine’s energy and railway infrastructure. President Macron swiftly condemned these actions, characterizing them as moves fundamentally opposed to any peaceful resolution. This incident sharply highlights the immediate need to finalize concrete security arrangements.

European leaders have previously voiced considerable apprehension regarding the US-brokered process, fearing that territorial concessions might be made without securing firm commitments for Kyiv’s defense. Reflecting this concern, France and the United Kingdom took the initiative on November 26 to establish a dedicated working group focused on security guarantees for Ukraine, involving key players such as the United States, NATO, and Turkey. The December 8 meeting is designed to consolidate the European position as diplomatic maneuvering continues amidst the ongoing military escalation.
