Where Evidence leads The Argument
Policy Research sits at the centre of what Westbrook does. Every publication starts from the same premise, that clear analysis, grounded in evidence rather than assumption, is what current debates on defence, security, and geopolitics are often missing. Our work spans position papers, briefings, and longer-form analysis, each produced with a single aim, reaching a conclusion that can actually withstand challenge, and that policymakers, journalists, and the public can put to direct use. We publish independently of government, political party, and any single funder, so that the only thing our conclusions answer to is the evidence behind them.
Defence
Defence policy determines what Britain can actually protect, and what it risks losing if current choices go unexamined. Our work in this area looks past headline spending commitments to the decisions that actually shape capability, procurement choices, force structure, and the trade-offs between what's affordable and what's necessary. We assess where current policy is being tested by changing threats and changing alliances, and where the gap between stated ambition and delivered capability is widest. The aim is analysis that's useful to people making these decisions now, not a general commentary on defence spending after the fact.
Security
Security threats no longer sit neatly inside a single department's remit. Critical infrastructure, hybrid and grey-zone tactics, cyber-enabled disruption, and economic coercion increasingly blur the line between what's traditionally handled by defence, policing, or intelligence and the gaps between those responsibilities are often where real vulnerability sits. Our work in this area looks at the threats that fall between departmental lines, and at who should actually own the response when a single ministry's remit isn't sufficient. The aim is to name the gap clearly enough that it can be closed, rather than left to whichever department happens to notice it first.
Geopolitics
Geopolitics is where Britain's alliances, interests, and leverage are actually tested, not in abstract principle, but in the specific decisions a government makes when those things come into tension with each other. Our work in this area examines Britain's post-Brexit alliances, its relationships with established and emerging powers, and the trade-offs involved in a world where old assumptions about alignment and burden-sharing no longer hold automatically. The aim is to be specific about where Britain's interests actually lie, rather than defaulting to whichever position happens to be diplomatically comfortable at the time, and to make clear what the practical consequences of a given position would be.
