What is a Vice-Minister?

The term "vice-ministerial" is not commonly used in English. However, based on the context of your question, I can infer that you are asking about the meaning of the term "vice-ministro" in Spanish.

In Spanish, "vice-ministro" refers to a high-ranking official who serves as a deputy or assistant to a minister in a government department or ministry. The term is often used in countries where the government is organized into ministries, and each ministry has a minister at its head and several vice-ministers who assist them.

In essence, a vice-minister is a senior official who helps the minister with their duties and responsibilities, and can act as an interim replacement for the minister if needed. They may be responsible for overseeing specific areas of the ministry's work, such as budgeting, policy development, or implementation of programs.
