FACTBOX-Who might succeed Ethiopia's PM Meles Zenawi?

ADDIS ABABA, Aug 21 (Reuters) - After weeks of absence,

Ethiopia announced on Tuesday the death of long-serving Prime

Minister Meles Zenawi after he succumbed to an undisclosed

illness.

So who might succeed him? The Horn of Africa country has

kept a tight lid on the affair but here are a few names that

have been widely touted:

HAILEMARIAM DESALEGN

Soft-spoken and humble, yet politically shrewd is how some

diplomats in the Ethiopian capital, Addis Ababa, describe the

47-year-old deputy to Meles.

A former university dean, Hailemariam will be sworn in as

acting prime minister by parliament, before the ruling party

holds a congress meeting to select a successor. A date has not

yet been set.

Hailemariam quickly rose through the ranks when he turned to

politics, serving as president of the Southern Nations,

Nationalities and People's Region in the south west of the

country from 2001 to 2006 prior to being named as an advisor to

Meles.

His pick as Meles' deputy in 2010 was a major surprise,

partly due to his relative young age. He is widely seen as the

late leader's protege.

He also replaced Meles as chair of a number of parliamentary

committees in the past few years, a tell-tale sign of grooming,

diplomats say.

AZEB MESFIN

The wife of Meles and mother of his three children, Azeb's

rise from closely-guarded first lady to a workaholic politician

and activist has inevitably raised speculation that Ethiopia

would do "a Kirchner" - in reference to Argentina's experience

in which the current leader Christina replaced her husband upon

his death.

A member of parliament, she has won numerous accolades for

her anti-HIV/AIDS campaign in the past few years and is chair of

a parliamentary body on social affairs.

She remains a polarising figure, however, with some members

of the country's ferociously anti-government Diaspora often

criticising her business activities.

TEWODROS ADHANOM GHEBREYESUS

Educated in Britain, Tewodros has been health minister since

2005 and has a string of achievements under his belt - including

a significant reduction in Ethiopia's child mortality rate -

that have won him international respect.

Tewodros has an outside chance for the posting. He told

Reuters in 2010, when Meles announced short-lived retirement

plans, he did not want to be prime minister. But he is also a

popular figure in his party, the ruling Ethiopian People's

Revolutionary Democratic Front.

ALEMAYEHU ATOMSA

Alemayehu is seen as a possible compromise candidate.

Alemayehu, currently head of the OPDO party that is allied

to Meles' EPRDF, is an Oromo, an ethnic group which, though

Ethiopia's largest in number, have never taken centre-stage

politically.

Meles was a Tigrayan, an ethnic group that accounts for just

6 percent of the population but came to dominate the political

establishment under Meles.

The Amhara ethnic group traditionally ruled the country and

are likely to lobby for one of their ruling party members to

take over after Meles' death.
