US at 250: Separation vs. concentration of power – America’s enduring constitutional debate

The third session in the US at 250 mini-series explores how checks and balances continue to shape American democracy.

Event date and time: 17 September 2026 — 17:00 TO 18:00 BST

Event location: Hybrid — Chatham House and Online

As the United States approaches the 250th anniversary of its Constitution, debate is growing over whether power remains balanced across government institutions. The US constitutional system faces scrutiny amid disputes over executive, judicial and administrative authority. These debates raise broader questions about the resilience of the US constitutional system.

This event discusses:

  • How has the separation of powers evolved over the past 250 years?
  • Does the Constitution effectively prevent the concentration of power?
  • What impact have the administrative state and judiciary had on institutional balance?
  • Which reforms could strengthen accountability and constitutional resilience?
  • How well is the Constitution equipped to meet future political challenges?
