Tanzania's new President John Magufuli was sworn into office 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.

"I promise to work to the best of my ability to deliver our election pledges," Magufuli said after taking the oath of office.

"We are aware of the trust and enormous responsibility that you have assigned us ... but with God's guidance, people's cooperation and goodwill our nation can prosper."
