With more than 70 percent of the vote counted on Saturday, the People's Movement for the Liberation of Angola (MPLA) secured over 74 percent of the vote in Friday's elections, Reuters reported.
The MPLA's closest challenger, the Union for the Total Independence of Angola (UNITA), gained about 18 percent of the vote while the CASA-CE party got nearly 5 percent of the vote, the National Elections Commission announced.
The MPLA election victory means the 70-year-old Dos Santos, who has been in office for 33 years, will serve another five-year term as president of Africa's second-largest oil producer.
The landslide MPLA victory in the third election since the country gained its independence from Portugal in 1975 was widely anticipated.
“These results show that the MPLA continues to be the party of the people and that we obtained a majority that will allow us to keep on growing the country in stability," MPLA spokesman Rui Falcao said.
The MPLA took 81 percent of the vote in the last elections in 2008.
