China congress: No heir apparent as Xi reveals top leadership
China has revealed its new senior leadership committee, breaking with tradition by not including a clear successor to President Xi Jinping.
The omission cements Mr Xi's grip on leadership for the next five years, a day after his name and his teachings were written into the constitution.
But it raises questions over whether Mr Xi, 64, intends to rule beyond 2022.
Five new appointments were made to the seven-member Politburo Standing Committee, China's most powerful body.
Why does the Politburo Standing Committee matter?
The committee is the top body of China's all-powerful Communist Party. Its role is to discuss and decide on major policy issues.
The party's constitution says China's top leader must also be a member of the standing committee. So appointments are keenly watched.
In the new line-up, Premier Li Keqiang, 62, is the only member to retain his position, apart from Mr Xi.
What kind of signal does the new line-up send?
Chinese leaders have traditionally hinted at possible heirs through committee reshuffles at the beginning of their final term.
There had been speculation that Mr Xi would elevate his protégé Chen Miner and Guangdong party secretary Hu Chunhua, both of whom are in their 50s - young enough to be credible successors.
But the fact that the new appointees were all in their 60s, and likely to retire at the end of this five-year term, sends a different signal.
The absence of any younger members will fuel speculation about Mr Xi's long-term intentions.
Could Xi break the 10-year rule?
The tradition emerged in the 1990s, when veteran leader Deng Xiaoping sought to avoid a repeat of the chaos that had marked the Mao era and its immediate aftermath.
Mr Xi's two predecessors have followed the orderly pattern of succession. But since he came to power in 2012, he has shown his readiness to write his own rules.
ReutersThe party voted on Tuesday to entrench Mr Xi's name and ideology. The unanimous vote to incorporate "Xi Jinping Thought" into the constitution significantly strengthens Mr Xi's political control.
Even if he decided to stand down in 2022, his influence is now so great that he could continue to effectively rule the country.
Analysis: On the offensive

Breaking the mould on the succession, as with so much else, is part of the Chinese president's New Era, as he has termed it.
But don't imagine that now the Congress is over, you can forget about Mr Xi's New Era. In the clash of political civilisations, he has put China on the offensive.
In his speech to Congress, he set out a vision not just for the five years ahead but for 30, and talked of a socialist model which provides, "a new option for other countries and nations".
At home China is accelerating its ability to listen to every call and track every face, online posting, movement and purchase. Expect it now to export not just the governance model but the cyber weapons to make that work.
Even as the party unveiled its new leadership, it excluded major Western news organisations from the ceremony.
Officially no reason was given for barring the BBC, Financial Times, Economist, New York Times and Guardian, but unofficially journalists were told that their reporting was to blame - another sign of Xi's determination to control the message at home and abroad.
How has Xi changed China?
Mr Xi has assumed an unprecedented number of positions since coming to power in 2012, including the title of a "core" leader of China.
His first term has been marked by significant development, a push for modernisation and increasing assertiveness on the world stage.
It has also seen growing authoritarianism, censorship and a crackdown on human rights.
He has spearheaded a sweeping anti-corruption campaign which has seen more than a million officials disciplined. It has been seen by some as a massive internal purge of opponents.
What is Xi 'thinking'?
At first glance, "Xi Jinping Thought" may seem like vague rhetoric, but it describes the communist ideals Mr Xi has continuously espoused throughout his rule.
Its 14 main principles emphasise the Communist Party's role in governing every aspect of the country, and also include:
- A call for "complete and deep reform" and "new developing ideas"
- A promise of "harmonious living between man and nature" - this is a call for improved environmental conservation, and could refer to the stated aim to have the bulk of China's energy needs supplied by renewables
- An emphasis on "absolute authority of the party over the people's army" - which comes amid what analysts call the largest turnover of senior military officials in modern Chinese history
- An emphasis on the importance of "'one country two systems" and reunification with the motherland - a clear reference to Hong Kong and Taiwan
