Our Whitehall Briefings connect Whitehall officials and other key stakeholders for discussions on a range of topical geopolitical, geoeconomic and geostrategic issues, as well as domestic issues associated with the United Kingdom’s leadership on the global stage. A prominent Whitehall official discusses their knowledge and expertise before invited guests engage in discussion and offer valuable input and ideas.
The Whitehall Briefings take place bi-monthly at the In and Out Naval and Military Club. Events are by invitation only and take place strictly off-the-record.
