The new Conflict, Stability and Security Fund (CSSF) will bring together resources from across Government, and draw on the most effective combination of defence, diplomatic, development, security and intelligence, and other cross-Government capabilities. The CSSF will build on the Building Stability Overseas Strategy, and the National Security Strategy. These capabilities are at the heart of the Prime Minister's "golden thread" and can play a vital role in tackling the root causes and impacts of conflict and instability in fragile states. The National Security Strategy identified climate change, energy issues and resource competition as drivers of global insecurity. These are therefore clear priorities for the NSC (National Security Council) and will be considered in conjunction with other NSC conflict drivers and priorities.
