Election paves the way for him to replace Shinzo Abe as the country's next prime minister on Wednesday.

Yoshihide Suga has been elected leader of Japan's governing Liberal Democratic Party (LDP), paving the way for him to become the country's next prime minister.

As expected, Suga easily won Monday's internal vote to pick a successor to Prime Minister Shinzo Abe, who announced in August that he would step down due to health problems.

Currently the chief cabinet secretary, Suga took 377 of a total of 534 votes against the two other contenders, former Defense Minister Shigeru Ishiba and former Foreign Minister Fumio Kishida.

Given the LDP's legislative majority, Suga is expected to handily win a parliamentary vote on Wednesday.

A powerful government adviser and spokesman, 71-year-old Suga is seen as promising stability and a continuation of Abe's policies.

He has specifically said his candidacy was motivated by a desire to continue the outgoing prime minister's programs.

Ishiba, who is popular with the Japanese public but less so within his own party, won just 68 votes, with Kishida, who was once considered Abe's favored successor, taking 89.

Abe, who smashed records as Japan's longest-serving prime minister before being forced to resign after a recurrence of ulcerative colitis, declined to publicly endorse any candidate.

The son of a strawberry farmer, Suga was raised in Japan's northern Akita region, and the issues of rural areas suffering depopulation are said to be among his top concerns.

But not much is known about his personal ideology, and he is generally viewed as an adherent of neither the LDP's most hawkish nor its more reformist wings.
