Politics

Solomon Islands is a constitutional monarchy and has a parliamentary system of government. As King of Solomon Islands, Charles III is head of state; he is represented by the Governor-General who is chosen by the Parliament for a five-year term. There is a unicameral parliament of 50 members, elected for four-year terms. However, Parliament may be dissolved by majority vote of its members before the completion of its term.

Parliamentary representation is based on single-member constituencies. Suffrage is universal for citizens over age 21. The head of government is the Prime Minister, who is elected by Parliament and chooses the cabinet. Each ministry is headed by a cabinet member, who is assisted by a permanent secretary, a career public servant who directs the staff of the ministry.

Solomon Islands governments are characterised by weak political parties (see List of political parties in Solomon Islands) and highly unstable parliamentary coalitions. They are subject to frequent votes of no confidence, leading to frequent changes in government leadership and cabinet appointments.

Land ownership is reserved for Solomon Islanders. The law provides that resident expatriates, such as the Chinese and Kiribati, may obtain citizenship through naturalisation. Land generally is still held on a family or village basis and may be handed down from mother or father according to local custom. The islanders are reluctant to provide land for nontraditional economic undertakings, and this has resulted in continual disputes over land ownership.

No military forces are maintained by Solomon Islands although a police force of nearly 500 includes a border protection unit. The police also are responsible for fire service, disaster relief, and maritime surveillance. The police force is headed by a commissioner, appointed by the governor-general and responsible to the prime minister. On 27 December 2006, the Solomon Islands government took steps to prevent the country's Australian police chief from returning to the Pacific nation. On 12 January 2007, Australia replaced its top diplomat expelled from Solomon Islands for political interference in a conciliatory move aimed at easing a four-month dispute between the two countries.

On 13 December 2007, Prime Minister Manasseh Sogavare was toppled by a vote of no confidence in Parliament, following the defection of five ministers to the opposition. It was the first time a prime minister had lost office in this way in Solomon Islands. On 20 December, the parliament elected the opposition's candidate (and former Minister for Education) Derek Sikua as prime minister, in a vote of 32 to 15.

In April 2019, Manasseh Sogavare was elected as prime minister for fourth time, causing protests and demonstrations against the decision.
