- Through the E3 format (UK, France, Germany) he coordinated European security policy, notably on Ukraine and responses to US demands such as securing the Strait of Hormuz.
- His government secured an EU‑UK Security and Defense Partnership, but limited UK access to the EU’s SAFE defence fund highlighted lingering financial hurdles.
- The EU‑UK summit scheduled for July 22 was postponed, signalling Brussels’ wait for a new British leader to define the post‑Brexit relationship.
- Andy Burnham, former Manchester mayor, is widely tipped as Starmer’s likely successor; he is seen as pro‑European but may prioritize domestic affairs over foreign policy.

- Starmer’s legacy in Europe rests on his tangible contributions to Ukraine’s defence and the institutionalisation of a structured EU‑UK security dialogue, even as his domestic political capital waned.
Domestic Unpopularity versus European Esteem
Keir Starmer announced his resignation on Monday, a move that reflected declining popularity among British voters who have criticised his leadership on cost‑of‑living issues and internal Labour Party divisions. Yet, abroad the reaction was markedly different. European leaders greeted his departure with gratitude, underscoring the stark contrast between his domestic standing and his reputation as a reliable partner on continental security matters. This divergence highlights how foreign‑policy achievements can sometimes insulate a leader from internal political tides, at least in the eyes of allies.
Reactions from EU and Ukrainian Leaders
European Commission President Ursula von der Leyen took to social media to thank Starmer, writing that “European and Ukrainian security is stronger because of you.” French President Emmanuel Macron echoed this sentiment, lauding Starmer’s involvement in the EU’s “coalition of the willing” for Ukraine and his efforts to revive EU‑UK relations after Brexit. Ukrainian President Volodymyr Zelenskyy also posted a note of appreciation on platform X, emphasizing that Starmer’s consistent backing had been vital during the war with Russia. These endorsements collectively illustrate the high regard in which Starmer was held across the continent.
Leadership in the Coalition of the Willing
Starmer’s most conspicuous European role emerged through his co‑leadership, alongside Macron, of the coalition of 35 states committed to supporting Ukraine. The alliance channels military aid to Kyiv and pledges to assist with long‑term defence planning should a ceasefire materialise. By championing this initiative, Starmer helped translate political solidarity into concrete material support, reinforcing Ukraine’s resilience against Russian aggression. His active participation signalled the UK’s willingness to shoulder a share of the security burden traditionally borne by the United States.
Expert Assessment of Starmer’s Reliability and Challenges
Olivia O’Sullivan, director of the UK in the World programme at Chatham House, described Starmer as a “very active and reliable partner” within the coalition. She noted that he worked closely with fellow leaders to devise strategic approaches for securing peace, even as he grappled with meeting his self‑imposed military‑spending targets. O’Sullivan pointed out that funding shortfalls are a structural issue that any successor will inherit, suggesting that Starmer’s difficulties were symptomatic of broader fiscal constraints rather than personal failure.
The E3 Format and EU‑UK Security Cooperation
Beyond the coalition, Starmer leveraged the E3 framework—comprising the UK, France and Germany—to shape European foreign and security policy. O’Sullivan highlighted that the E3 has been instrumental in formulating joint statements on issues ranging from Ukraine to responses to US demands, such as securing the Strait of Hormuz. The forum also facilitated the signing of the EU‑UK Security and Defense Partnership in May 2023, a landmark accord designed to regularise defence dialogue and joint initiatives post‑Brexit.
Strategic Impact of the E3 on Broader Security Issues
The E3’s influence extends beyond bilateral concerns. For instance, the group has used its collective voice to articulate European positions on how the continent should respond to American pressure regarding maritime security in the Strait of Hormuz. By aligning France, Germany and the UK, the E3 can present a unified front that mitigates the unpredictability of US foreign policy under shifting administrations. Starmer’s stewardship helped ensure that the UK remained a consequential node in this triangular diplomacy.
Limitations: Access to Defence Funding and Fiscal Restraints
Despite these successes, Starmer’s tenure encountered practical limits. The UK secured only restricted access to the EU’s SAFE (Security Action for Europe) programme, a €150 billion fund aimed at accelerating defence readiness among member states. British officials balked at paying the required participation fee, thereby curtailing London’s ability to fully reap the initiative’s benefits. This episode underscored the ongoing tension between Britain’s ambition to deepen defence ties with the EU and its domestic fiscal prudence.
Post‑Brexit Efforts to Reset EU‑UK Relations
Starmer had campaigned on delivering a “fresh start” with the EU, and his government made tangible progress in several areas. Initiatives to revive youth mobility schemes, expand student exchange programmes, and resolve fisheries disputes exemplified a pragmatic approach to rebuilding trust. The EU‑UK Security and Defense Partnership, signed during his premiership, institutionalised these efforts, providing a framework for regular high‑level talks and cooperative projects on defence and security.
Postponement of the EU‑UK Summit and Awaiting New Leadership
On the day of Starmer’s resignation, European Council President António Costa announced that the EU‑UK summit originally slated for July 22 had been postponed indefinitely. The delay signals Brussels’ preference to wait for a clear British leadership direction before re‑engaging on the substantive agenda. It also reflects the EU’s cautious stance toward a period of potential policy flux in London, preferring stability over premature negotiations.
Speculation on the Successor: Andy Burnham’s Prospects
Political analysts widely anticipate that Andy Burnham, the former mayor of Manchester, will succeed Starmer. Burnham is regarded as broadly pro‑European, having expressed support for closer ties with the continent on issues such as trade and regulation. However, O’Sullivan cautions that his track record shows a stronger focus on domestic policy—particularly housing, transport and local governance—than on international affairs. Whether he will devote comparable energy to foreign‑policy portfolios remains uncertain, raising questions about the continuity of Starmer’s European initiatives.
Outlook for the Next Prime Minister and European Security
The incoming prime minister will inherit a mixed legacy: a solidified EU‑UK security partnership, active participation in the Ukraine coalition, and a functional E3 channel, but also lingering challenges such as defence‑funding constraints and the need to renegotiate fiscal commitments to EU programmes. Maintaining the momentum Starmer generated will require balancing domestic pressures with the expectation to remain a dependable security partner for Europe. The extent to which the next leader prioritises foreign affairs will determine whether the UK sustains its current influence or recedes into a more peripheral role within European strategic circles.
Conclusion: Starmer’s European Legacy
Keir Starmer’s premiership may be remembered domestically for its struggles, yet in Brussels and Kyiv his tenure is marked by concrete contributions to continental security. By championing the coalition of the willing, shaping E3 diplomacy, and formalising an EU‑UK defence accord, he helped bridge the post‑Brexit divide and reinforced a collective response to Russian aggression. While his departure invites recalibration, the institutional foundations he helped lay—particularly the Security and Defense Partnership and the E3 mechanism—offer a platform for the next British leader to build upon, should they choose to embrace the outward‑looking, security‑focused vision that characterised his time in office.
