BEIJING (Reuters) - China's largely rubber-stamp parliament chose former top graft-buster Wang Qishan, a key ally of President Xi Jinping, as vice president on Saturday, a widely expected move that nonetheless breaks with convention and underlines Xi's dominant authority.
Xi was also re-elected president by parliament, with no votes cast against him. The body is packed with party loyalists and there was no chance he would not win the vote.
Wang bowed twice and then walked over to Xi to shake his hand after the vote was announced inside Beijing's Great Hall of the People. Only one person voted against Wang out of the 2,970 votes cast.

Xi and Wang spoke only to pledge allegiance to the constitution, with Wang giving the podium an emphatic tap after he finished.
Known as "the firefighter" for his central role in tackling issues like corruption and domestic financial problems over the years, Wang also has experience dealing with the United States in his former role as a vice premier who led annual economic talks with Washington.
He was a major player in Xi's battle against corruption, with dozens of senior officials jailed during his tenure as the top graft-fighter, including the fearsome domestic security chief Zhou Yongkang, now serving life in jail.
Zhao Wanping, a delegate from the central province of Anhui, told Reuters Wang's election was in line with the will of the people, pointing to his anti-corruption efforts.
"Our country needs someone like him who will continue to step out and shoulder responsibilities for the people," he said.
Last Sunday, parliament voted to amend the constitution, which removed presidential and vice-presidential term limits, meaning Xi can stay in power indefinitely, a move the government has presented as widely welcomed despite criticism that has evaded the censors and seeped onto Chinese social media.
The party's People's Daily hailed Xi's unanimous re-election in an editorial on its WeChat account, using language once more associated with Mao Zedong to say he was a "leader loved and respected by the people" and the "helmsman of the country".
Wang's appointment has the potential to reshape what has traditionally been a ceremonial role. China's relationship with the United States is likely to be a key part of his remit, according to diplomats and sources with ties to the leadership.
"The vice president position in the PRC is not a very powerful one, but it depends who fills the job," said Jean-Pierre Cabestan, a China expert at Hong Kong Baptist University, referring to the country's formal name, the People's Republic of China.
Cabestan said Wang would likely be considerably more influential than his immediate predecessor, Li Yuanchao, given his close relationship with Xi and greater international profile.
But any effort by China to elevate formal exchanges with the United States on tricky trade issues, for example from a cabinet to vice presidential level, would require the White House's consent too. Wang also speaks no English.
China has been trying to head off a trade war with the United States, sending envoys to Washington in recent weeks, including Xi's top economic adviser, Liu He.

DELEGATE FROM HUNAN
Whether Xi could retain Wang in a senior role despite his reaching retirement age had been seen as a key measure of Xi's power and the subject of much speculation in the lead-up to this month's National People's Congress.
In January, Wang, who turns 70 in July, was named a parliament delegate with the central province of Hunan despite having stepped down from the elite seven-man Politburo Standing Committee during a five-yearly leadership transition in October.
Despite holding no official senior party role, Wang has taken center stage at plenary sessions this parliament, seated immediately next to the seven members of the Standing Committee, in a clear indication of his actual status.
At the opening session where Premier Li Keqiang presented the government's work report, Wang cut a relaxed figure, staring straight ahead impassively while other delegates busily read and jotted down notes.
Protocol at major political events, including seating arrangements and the order in which leaders are shown in state news bulletins, are tightly choreographed to convey a political message.
Wang cast his ballot on Saturday immediately after Han Zheng, the seventh-ranked and most junior Standing Committee member, drawing enthusiastic applause from the other delegates.
Wang has otherwise kept a relatively low profile at parliament so far, with no state media reports of any visits to other provincial delegations to rally legislators, as members of the Standing Committee have done, including Xi.
Cao Huiquan, a Hunan delegate who heads the province's Economic and Information Technology Commission, told Reuters last week that Wang had taken part in the Hunan delegation's discussions of Li's work report.
Cao said Wang paid particular attention to whether party cadres had sufficiently understood the spirit of the October Party Congress including "how to understand and get a handle of new areas of societal problems, the public's aspirations toward a better life, and uneven and insufficient economic development".
On Saturday, parliament also formally approved a government restructuring plan that merges China's banking and insurance regulators, gives new powers to policymaking bodies such as the central bank and creates new ministries.
