Secretary of State for Foreign and Commonwealth Affairs in the context of "Shadow minister"

The Conference of Lausanne was a peace conference held in Lausanne, Switzerland between Allies and Türkiye during 1922 and 1923 following the Turkish victory and the defeat of Allies in the Turkish War of Liberation and the following Armistice of Mudanya. Its purpose was the negotiation of a peace treaty after Turkish War of Liberation and Armistice of Mudanya and to replace the Treaty of Sèvres, which, under the new government of Mustafa Kemal Atatürk, was no longer recognized by Turkey.

The conference opened in November 1922, with representatives from Great Britain, France, Italy and Türkiye. The Grand National Assembly of Turkey selected İsmet İnönü, Rıza Nur and Chief Rabbi Chaim Nahum as their representatives. Lord Curzon, the British Foreign Secretary, was the co-ordinator of the conference, which he dominated. France and Italy had assumed that the Chanak Crisis had caused British prestige with Türkiye to be irrevocably damaged, but they were shocked to discover that Turkish respect for Britain was undiminished. British troops had held their positions at invaded Çanakkale, but the French had been ordered to withdraw.

The chief of the Secret Intelligence Service serves as the head of the Secret Intelligence Service (SIS, also commonly known as MI6), which is part of the United Kingdom intelligence community. The chief is appointed by the foreign secretary, to whom they report directly. Annual reports are also made to the prime minister.

The chief of the Secret Intelligence Service typically signs letters with a "C" in green ink. This originates from the initial used by Captain Sir Mansfield Smith-Cumming, when he signed a letter "C" in green ink. Since then the chief has been known as "C".

Government Communications Headquarters (GCHQ) is an intelligence and security organisation responsible for providing signals intelligence (SIGINT) and information assurance (IA) to the government and armed forces of the United Kingdom. Primarily based at The Doughnut in the suburbs of Cheltenham, GCHQ is the responsibility of the country's Secretary of State for Foreign and Commonwealth Affairs (Foreign Secretary), but it is not a part of the Foreign Office and its director ranks as a Permanent Secretary.

GCHQ was originally established after the First World War as the Government Code and Cypher School (GC&CS) and was known under that name until 1946. During the Second World War it was located at Bletchley Park, where it was responsible for breaking the German Enigma codes. There are two main components of GCHQ, the Composite Signals Organisation (CSO), which is responsible for gathering information, and the National Cyber Security Centre (NCSC), which is responsible for securing the UK's own communications. The Joint Technical Language Service (JTLS) is a small department and cross-government resource responsible for mainly technical language support and translation and interpreting services across government departments. It is co-located with GCHQ for administrative purposes.

The term "great power" has only been used in historiography and political science since the Congress of Vienna in 1815. Lord Castlereagh, the British Foreign Secretary, first used the term in its diplomatic context in 1814 in reference to the Treaty of Chaumont. Use of the term in the historiography of the Middle Ages is therefore idiosyncratic to each author. In historiography of the pre-modern period, it is more typical to talk of empires.

Gerry Simpson distinguishes "Great Powers", an elite group of states that manages the international legal order, from "great powers", empires or states whose military and political might define an era.
