It leaves the European Union (EU), the World Bank, the African Development Bank (AfDB) and Denmark as the four remaining donors, according to the finance ministry, local media reports.

It represents another blow to the government of President John Magafuli after the US pulled $472m (£331m) of funding for development projects because of concerns over recent elections in Zanzibar.

The Swedish embassy said in a statement that their decision was not connected to Zanzibar, but rather due to "corruption surrounding the energy sector" and the scheduled expiration of the current agreement.

The Republic of Ireland embassy said it had "no further plans to release budget support" and that the last payment was made in June 2015.
