Has Brexit broken Britain’s ruling class into warring factions?

MATCH OF THE DAY: Factionalized Elites UK 0 v EU 1 

Brexit was sold as a control play. On the Fund for Peace test for Factionalized Elites, it looks more like an own goal: by 2024 the UK is the worst side in this mini-league on this measure, scoring 5.8 against the EU’s 3.81, with higher numbers meaning worse fragmentation.

That matters directly to Keir Starmer, because a government cannot look competent if the state keeps converting disagreement into deadlock. The thesis is simple: Brexit did not heal Britain’s ruling class; it turned an old elite split into a governing system.

1 PROBLEM

The visible problem is not abstract instability but a governing class that no longer governs as one. Fund for Peace defines Factionalized Elites as fragmentation inside state institutions, elite brinkmanship, gridlock, nationalist rhetoric, and, in the worst cases, the absence of leadership accepted by the whole citizenry. On that measure, the UK moves from 3.6 in 2012 to 5.8 in 2024, while the EU moves from 3.25 to 3.81. Britain is not just above the EU average; it is also above Italy, Germany and France in the same comparison set on the official comparative analysis platform. The movement line is the real story: as the 2020 Fund for Peace Brexit analysis and the 2020 Fragile States Index report both note, the UK’s Factionalized Elites score worsened by 2.3 points in four years. Verdict: on this metric, Britain is now playing the hardest match against itself.

Why?

3 REASONS

PLAN — Britain failed the representative leadership test.
Fund for Peace’s clearest UK application sits under its Representative Leadership criteria: whether leadership is representative, whether elites are factionalized, whether reconciliation exists, and whether political competition is being processed through legitimate institutions.

In its Brexit analysis, Fund for Peace says that is exactly what worsening factionalization looks like: power struggles, political competition, weak political reconciliation, and gridlock between ruling elites. The key point is not that Britain lacked elections; Fund for Peace does not say the UK ceased to be electorally legitimate. Its point is harsher: the British governing class became less able to act as a leadership class accepted across the whole polity.

The EU had arguments, but it still had a route. Britain had mandates, but no settlement mechanism. 

Plan score: UK 2/10, EU 7/10 — one side could absorb conflict; the other kept staging it.

POLICY — identity conflict spilled into the state.
The second Fund for Peace cluster is Identity: national identity, nationalism, toxic rhetoric, stereotyping, scapegoating, separatist pressure, and cross-cultural respect. Here the UK evidence is unusually direct.

The 2018 Fragile States Index article says the Brexit referendum came amid “unprecedented levels of division and group grievance” in Britain’s social and political sphere, and warns that “divisive policy-making and rhetoric is simply incompatible with a country’s ability to thrive.” The 2020 report adds that the UK worsened on State Legitimacy by 0.6 points, while Factionalized Elites, Human Rights, and Security Apparatus each worsened by 0.3 points.

That is why this is not merely a Westminster story. Elite conflict spread outward into national identity, public discourse, and social trust. Brexit promised sovereignty; in practice it turned a constitutional question into an identity struggle. 

Policy score: UK 3/10, EU 7/10 — the temperature rose, and the thermostat broke.

PERFORMANCE — the rules stopped feeling shared.
Fund for Peace’s most powerful UK evidence under Equality and Equity is the 2019 prorogation episode. Johnson’s suspension of Parliament for five weeks was later ruled unlawful, and Fund for Peace argues that the episode eroded the shared acceptance of constitutional norms.

That matters because the UK’s unwritten constitution depends on a common understanding of the rules of the game; once those rules were no longer widely shared, elite competition stopped looking like ordinary politics and started looking like a legitimacy problem.

The Factionalized Elites methodology also includes Resource Distribution, but in the retrieved UK Brexit material Fund for Peace does not develop that strand directly; the real action is in representative leadership, identity, and constitutional legitimacy. That is the epiphany line: Brexit did not create every crack, but it turned the cracks into architecture. 

Score: UK 3/10, EU 8/10 — Europe kept the contest inside the rules; Britain started arguing about the rules themselves.

FINAL WHISTLE

Britain’s problem on Factionalized Elites is not that politics became loud. It is that representative leadership weakened, identity conflict intensified, and constitutional norms ceased to feel universally shared.

Fund for Peace’s judgment in its Brexit analysis is that Brexit was both catalyst and symptom: it exposed existing fractures, then sharpened them into a governing condition.

That is why the UK now sits behind the EU benchmark on this metric and why Starmer’s test is bigger than competence theatre. He has to prove that British government can once again turn rivalry into settlement, not merely headlines into postponement.

If he cannot, the risk is plain: more blocked reform, weaker legitimacy, and a country that keeps mistaking noise for control.
