Falkland Islands, but since "Saints" were re-awarded British citizenship in 2002, emigration to Britain by a wider range of wage-earners has accelerated due to the prospect of higher wages and better progression prospects. By 2018 Swindon, Wiltshire, had a concentration of people originating from Saint Helena, and therefore it got the nickname "Swindolena". Religion Most residents are Anglican and are members of the Diocese of St Helena, which has its own bishop and includes Ascension Island. The 150th anniversary of the diocese was celebrated in June 2009. Other Christian denominations on the island include the Roman Catholic (since 1852), the Salvation Army (since 1884), Baptist (since 1845) and, in more recent times, the Seventh-day Adventist (since 1949), the New Apostolic Church, and Jehovah's Witnesses (of which one in 36 residents is a member, the highest ratio of any country). The Roman Catholics are pastorally served by the Mission sui iuris of Saint Helena, Ascension and Tristan da Cunha, whose office of ecclesiastical superior is vested in the Apostolic Prefecture of the Falkland Islands. Government Executive authority in Saint Helena is vested in King Charles III and is exercised on his behalf by the Governor of Saint Helena. The Governor is appointed by the King on the advice of the British government. Defence and foreign affairs remain the responsibility of the United Kingdom. There are 15 seats in the Legislative Council of Saint Helena, a unicameral legislature, in addition to a Speaker and a Deputy Speaker. Twelve of the 15 members are elected in elections held every four years. The three ex officio members are the Chief Secretary, Financial Secretary and Attorney General, currently Susan O'Bey, Dax Richards and Allen Cansick respectively. The Executive Council is presided over by the Governor and consists of three ex officio officers and five elected members of the Legislative Council appointed by the Governor. There is no elected Chief Minister, and the Governor acts as the head of government. In January 2013 it was proposed that the Executive Council would be led by a Chief Councillor who would be elected by the members of the Legislative Council and would nominate the other members of the Executive Council. These proposals were put to a referendum on 23 March 2013 where they were defeated by 158 votes to 42 on a 10% turnout. Another referendum in 2021, however, saw the population approve the changes.
