Likoma Island (9,000 inhabitants) is the larger of two inhabited islands in Lake Malawi (being Chisumulu Island the smaller one). Both these islands lie just a few kilometres from Mozambique, and are entirely surrounded by Mozambican territorial waters, but belong to Malawi. They are therefore exclaves of Malawi. This came about because the islands were colonised by Anglican missionaries spreading east from Malawi, rather than by the Portuguese who colonised Mozambique.
