Beginning in the 1950s, the political history in Maldives was largely influenced by the British military presence in the islands. In 1954 the restoration of the sultanate perpetuated the rule of the past. Two years later, the United Kingdom obtained permission to reestablish its wartime RAF Gan airfield in the southernmost Addu Atoll, employing hundreds of locals. In 1957, however, the new prime minister, Ibrahim Nasir, called for a review of the agreement. Nasir was challenged in 1959 by a local secessionist movement in the three southernmost atolls that benefited economically from the British presence on Gan. This group cut ties with the Maldives government and formed an independent state, the United Suvadive Republic with Abdullah Afif as president and Hithadhoo as capital. One year later the Suvadive republic was scrapped after Nasir sent gunboats from Malé with government police, and Abdulla Afif went into exile. Meanwhile, in 1960 the Maldives had allowed the United Kingdom to continue to use both the Gan and the Hithadhoo facilities for a thirty-year period, with the payment of £750,000 over the period of 1960 to 1965 for the purpose of Maldives' economic development. The base was closed in 1976 as part of the larger British withdrawal of permanently-stationed forces 'East of Suez'.
