Former head of intelligence Diwani Athumani Msuya had on Tuesday been appointed as State House permanent secretary.

But he was replaced on Thursday by Mululi Majula Mahendeka - himself a former State House official.

No explanation was offered in a statement from the president's office that announced the changes.

Mr Msuya was appointed as head of Tanzania Intelligence and Security Services (TISS) in September 2019 by former President John Magufuli.
