Tanzania’s new President John Magufuli was sworn into office on Thursday along with the east African nation’s first female vice-president to huge cheers from crowds. Magufuli’s win in the October 25 poll with over 58 percent of votes cemented the long-running Chama Cha Mapinduzi (CCM) party’s firm grip on power.Vice-President Samia Suluhu Hassan, who comes from Zanzibar, was also sworn in at a stadium in the economic capital Dar es Salaam, an AFP reporter at the ceremony said. Elections were largely peaceful, but the opposition said the vote was rigged and also claimed victory, while semi-autonomous Zanzibar –which also voted for its own president – annulled polls over irregularities.
