Which of the following is NOT a role associated with the First Lord of the Treasury?

The First Lord of the Treasury primarily functions as the head of the UK government's executive branch and is closely associated with managing fiscal policy and the overall financial administration of the country. This includes overseeing the Treasury and the central government’s economic strategy. The role is often held by the Prime Minister, who also serves as the leader of the ruling party, further linking the position with the governance and political leadership of the country.

In contrast, the designation of Secretary of State typically refers to a different cabinet level position within the UK government, responsible for specific departments such as Foreign Affairs or Health, rather than the broader role of managing treasury affairs or the government's overall direction. Thus, it does not align with the responsibilities traditionally held by the First Lord of the Treasury.
