But who is in control when it comes to foreign affairs? Legally standing it would seem that the Foreign Secretary who oversees conduct on foreign policy in the United Kingdom, even though this has not always been varying from Prime minister to Prime Minister. For the Prime Minister alone holds the ability to declare war and or deploy British troops. This obviously like everything in British law leaves a lot of room for power shifting depending on Prime ministers and their agenda while in Switzerland the Federal Department of Foreign Affairs has a specific power in troops. This is because Switzerland's are never deployed for combat but for peacekeeping affairs mostly part of NATO peacekeeping missions this is quite different than the United Kingdoms extensive involvement in foreign affairs. .
Former Prime Minister Tony Blair has proven that this power can sway to that of the executive due to no specific written laws on anything specifically military power. That is the style of policy-making changes dramatically depending on who is leading the country. During the New Labour reign of power, the most important decisions on foreign policy were not conducted from the Foreign Secretary but from inside the Cabinet of the Prime Minster. This leadership by Tony Blair showed his intentions of being an "interventionalist" as Great Britain was part of several military operations such as Desert Fox in Iraq and Barras in Sierra Leone along with others. In this, it is the Prime Minister's decision whether to send troops into combat or not and former Prime Minister Tony Blair choose to consult a small group within his cabinet rather than the whole cabinet itself, giving more power to the Prime Minister.
Today Great Britain regrets being part of the European Union and taking care of poor European Nations at the cost of the United Kingdom. Great Britain is constantly pushing policy that furthers themselves from the European Union including that of not having the Euro as their currency rather keeping the British pound which is significantly stronger.
