Thailand's coup leader was elected prime minister Thursday by the kingdom's junta-appointed legislature without a single opposing vote, raising fears of a new era of "strongman" leadership.
Army chief General Prayut Chan-O-Cha, 60, who ousted an elected government in a bloodless takeover on May 22, was the only contender for the premiership.
The move by the top general to take the post, while also remaining junta boss, is seen as cementing the military's control of the politically turbulent nation.
"He has taken all the power so I cannot help but worry that we will enter the period of a strongman," said Gothom Arya, a lecturer at Thailand's Mahidol University.
The junta, formally known as the National Council for Peace and Order (NCPO), has ruled out holding new elections before around October 2015, despite international appeals for a return to democracy.
"The generals clearly do not plan to restore democracy," said Sunai Phasuk, senior researcher at New York-based Human Rights Watch.
"Instead of paving the way for a return to democratic civilian rule, the NCPO has granted itself unchecked authority to do almost anything it wants, including committing rights abuses with impunity."
Prayut, who is due to retire as army chief in September, is seen as a staunch opponent of fugitive former premier Thaksin Shinawatra, whose overthrow in an earlier coup in 2006 triggered Thailand's long-running political crisis.
Thaksin -- whose sister Yingluck was dismissed as premier in a controversial court ruling just before this year's coup -- fled Thailand in 2008 to avoid prison for a corruption conviction.
Following the 2006 putsch -- now widely seen as a failure in light of the subsequent political turmoil -- the junta handed the reins to an army-backed premier who oversaw a series of policy blunders that damaged the economy.
Prayut in contrast "will be hands on, and convinced of his vision for the restructuring of the Thai political order," said Michael Montesano, a research fellow at the Institute of Southeast Asian Studies in Singapore.
"The goal is a severely constrained form of 'democracy' that holds the freely expressed will of the electorate in check and seeks to freeze Thailand in an imagined past."
- Reform or repression? -
The army rulers say they want to reform Thailand to end years of political turbulence and street violence, but critics see the takeover as an attempt to wipe out Thaksin's influence.
The junta has vowed to remain in place in parallel to the future government, which will be nominated by Prayut as prime minister.
He was backed by 191 members of the 197-strong assembly, with three abstentions and three voters absent. No other candidate stood against him.
"We need a leader who can help the country through the crisis," said assembly member Tuang Untachai, who proposed Prayut as premier.
"We have to set aside all conflicts and move the country forward."
Prayut is often described as the architect of an army crackdown on a pro-Thaksin "Red Shirt" rally in Bangkok in 2010 that left dozens dead.
Before seizing power, the golf lover and father of twin daughters had said he would not allow Thailand to become another "Ukraine or Egypt".
Thaksin, who is reviled by much of Thailand's Bangkok-based royalist elite, lives in Dubai but he or his parties have won every election since 2001.
Since seizing power the junta has abrogated the constitution, curtailed civil liberties under martial law and summoned hundreds of opponents, activists and academics for questioning.
"This is not a climate for an election to be held freely and fairly," said Sunai at Human Rights Watch.
"Even after the next election, scheduled for the end of 2015, the NCPO will stay on with overarching power. This is a military rule that gives no hope for democracy to be restored in Thailand."
The United Nations' human rights office on Wednesday warned of "chilling effects" on freedom of expression under the junta, following recent arrests and jail sentences for insulting the monarchy.
