The political head of each of some 10 federal ministries – such as the Ministry of Education and the Ministry of Justice and Legal affairs – is a minister. Ministers are appointed by the governor-general, on the advice of the prime minister, from among members of the National Assembly. Nevis has its own legislature, however the central government is responsible for overall policy formation. Every department of the government of St Kitts and Nevis is under the supervision of a permanent secretary whose office is a public office. There also exists a secretary to the Cabinet whose office is a public office and whose roles include arranging the business for, and keeping the minutes of, the Cabinet and conveying the decisions of the Cabinet to appropriate persons and authorities.
