Country swears in Lourenco, first new president for 38 years

Jose Eduardo dos Santoss 38-year reign over Angola finally came to an end Tuesday when his hand-picked successor Joao Lourenco was inaugurated as president at a ceremony in Luanda.

Lourenco read an oath in which he vowed "on my honour to devote myself" to the role of president, as he took power after the ruling MPLA party won last month's election.

Dos Santos, who was at the ceremony but is reportedly in poor health, surprised many by announcing his retirement earlier this year, saying he would not be a candidate in the election.

The People's Movement for the Liberation of Angola (MPLA) has governed since Angola's hard-fought independence from Portugal in 1975, with Dos Santos taking power in 1979.

The party won 61 percent of the vote in August, a sharp drop in support from the previous election in 2012 as the country suffers an economic crisis triggered by the fall in oil prices.

Lourenco, 63, until recently defence minister, has vowed to attract more foreign investment and said he wants to be recognised as a leader who brought an "economic miracle" to the southern African country.

Though seldom seen in public, Dos Santos, 75, has been a looming presence in daily life for as long as most Angolans can remember, maintaining fierce control over the country throughout its devastating civil war and a short-lived oil boom.

Dos Santos's reign saw the end of the 1975-2002 war and a post-conflict investment boom as the country exploited its oil reserves.

But the slump in crude prices in 2014 hit the country hard.

Dos Santos was Africa's second-longest-serving leader -- one month shy of Equatorial Guinea's Teodoro Obiang Nguema.

Nguema was present at the ceremony, along with President Paul Kagame of Rwanda, Democratic Republic of Congo President Joseph Kabila, South African President Jacob Zuma and other African leaders.

Dos Santos's regular visits to Spain for "private" reasons fuelled criticism that the state of his health was being hidden from ordinary Angolans.

Earlier this year, his daughter Isabel -- who has become a billionaire and Africa's richest businesswoman under his rule -- was forced to deny rumours that he had died in Spain.

Amnesty International called for Lourenco to "guide the country out of the spiral of oppression" and castigated Dos Santos's "appalling human rights record".

Dos Santos is to remain MPLA party chief, and new laws limit the unfettered presidential power he enjoyed.
