This purpose-built Westminster venue is no stranger to high-profile clients. Its 32 event spaces hold up to 2,500 delegates, and conferences and exhibitions work well here. A major refurb, including a renovated façade, new breakout spaces and improved lighting, was recently completed. We’re big fans of the Churchill, whose slightly raked seating means everyone gets a good view. The larger rooms work well for banquets and drinks receptions.
