PERSPECTIVE PEACE AND SECURITY UK-GERMAN DEFENCE& SECURITY COOPERATION The growing prospects Ed Arnold September 2024 The UK-German relationship is a priority for the new UK Government and an additional two Joint Declarations have already been signed since the Labour Party came to power, with negotiations for a bila­teral Treaty started. As Russia’s war against Ukraine continues and the Euro-Atlantic security environ­ment deteriorates, the ration­ale for stronger UK-German cooperation is growing. The scope for a UK-German agreement appears to be wid­er than just defence and secu­rity, to incorporate economic benefits and other shared so­cial challenges. However, an increase in ambition will also increase the risks to delivery and a meaningful relationship.
