The victory margin was a surprise - many analysts had predicted a tighter race after four opposition parties united behind Mr Lowassa's candidature. It boiled down to Mr Magufuli's popularity, which superseded that of the governing Chama Cha Mapinduzi (CCM) that has dominated politics since independence from British rule in 1961. So what are the five big challenges he faces once in office? Change was the buzzword during the election campaign. Now people will expect him to engage in a major house-cleaning exercise by showing the door to corrupt government officials and old-school public servants. This will pose a huge political risk, as they are well-entrenched in CCM. But Mr Magufuli, the former works minister, will have to tackle corruption head-on, as Tanzanians have had enough of it.

Mr Magufuli will be hard-pressed to meet their demands - almost all state schools are short of desks, books and teachers. With last week's local elections in Zanzibar scrapped because of alleged rigging, Mr Magufuli will have to make sure that a re-run takes place, and that it is free and fair. When Mr Kikwete came to power, he promised to keep a close eye on the semi-autonomous islands, which are popular with tourists. But as he leaves the office, more than 60% of Zanzibaris want more autonomy for the archipelago - an indication of their dissatisfaction with the union.
