Three Emerging Security Challenges for the UK

In light of the planned 2015 Strategic Defence and Security Review, it is timely to consider afresh the global security landscape and the UK's place within it. What does “security” mean in this context, and what challenges does the UK face? Following a discussion of the meaning of “security”, the article will identify three broad themes from which security challenges for the UK emerge. These are: (1) cyberspace and the digital age; (2) change and the current international system; and (3) inequality within the UK. By examining recent developments in each of these areas, it will be argued that there are good reasons for these challenges to remain important in thinking about British security over the medium to longer term.
