Japan's governing party has elected Yoshihide Suga as its new leader to succeed Shinzo Abe, meaning he is almost certain to become the country's next prime minister.
Last month Mr Abe announced his resignation due to health reasons.
Mr Suga, 71, serves as chief cabinet secretary in the current administration and was widely expected to win.
He is considered a close ally of Mr Abe and likely to continue his predecessor's policies.
Mr Suga won the vote for the presidency of the conservative Liberal Democratic Party (LDP) by a large margin, taking 377 of a total of 534 votes from lawmakers and regional representatives.
Now that the LDP has chosen its new leader, there will be another vote on Wednesday in parliament, where he is almost certain to be made prime minister because of the LDP's majority.
Taking over mid-term, Mr Suga is expected to finish the rest of the current period, until elections in September 2021.
Who is Yoshihide Suga?
Born the son of strawberry farmers, Mr Suga is a veteran politician.
Given his central role of chief cabinet secretary in the administration, he is expected to provide continuity heading an interim government until the 2021 election.
"Shinzo Abe and the other party bosses picked and joined the bandwagon for Mr Suga precisely because he was the best 'continuity' candidate, someone who they think could continue Abe government without Abe," Koichi Nakano, dean and political science professor at Tokyo's Sophia University, told the BBC.
While not considered the most energetic or passionate politician, Mr Suga has a reputation of being very efficient and practical.
One of his most prominent appearances recently was during the transition from past emperor Akihito to the current one Naruhito in 2019. It fell to Mr Suga to unveil the name of the new Reiwa era to the Japanese and global public.

Observers suggest that by then, the party dynamic could shift to put a more vibrant man at the helm who can reach a wider general electorate.
Who else was running?
Two other contenders had thrown their hats in the ring.
Fumio Kishida served as foreign minister under Shinzo Abe, but for the past three years was heading the party's policy research council. Compared to Mr Suga, the 63-year old brought more international diplomatic experience to the table but lacked the endorsement by the outgoing prime minister.
The third contender was Shigeru Ishiba, a former LDP secretary-general and one time defence minister in an earlier Abe cabinet.

Even though neither he nor Mr Kishida were considered to have a realistic chance against Mr Suga, their bids might have put them in a good position for the 2021 general election once the current term is up.
What is Japan's political outlook?
The leadership transition comes at a difficult time for the country. Japan is still struggling with the coronavirus pandemic which has caused its biggest economic slump on record.
Mr Abe's long-standing project of kickstarting the economy, dubbed Abenomics was, even before the pandemic hit, still a work in progress and the country has seen several years of stagnation, recession or only very slow growth.
There's also unfinished business in the government's plans to reform the post-war pacifist constitution. Mr Abe wanted to change a section in the constitution to formally recognise Japan's military, which is currently called the Self Defence Force and is essentially barred from participating in any international military mandates.
For all those projects, a new administration under Mr Suga could provide stability.

"The only slogan he came up with is "Self help, mutual help, and public help" - emphasising neoliberal self-help and self-responsibility at the time of [a] pandemic that is exposing a whole lot of people to economic vulnerability."
New general elections for the Diet, the lower house, are scheduled for September 2021 and by then, there will likely be another leadership contest within the LDP.
That contest will be more about who can win over the general electorate - rather than merely promise continuity, observers say.
Why did Shinzo Abe resign?
Mr Abe said he did not want his illness to get in the way of decision making, and apologised to the Japanese people for failing to complete his term in office.

Last year, he became Japan's longest serving prime minister. His current period in office began in 2012.
He abruptly resigned from a previous term as prime minister in 2007 also because of his chronic condition.
