Fumio Kishida, the new leader of the Liberal Democratic Party and the nation's next prime minister, will tap former economy minister Akira Amari to be the ruling party's secretary-general, party sources said Thursday.

Kishida also picked former internal affairs minister Sanae Takaichi, who lost to him in the party's presidential race Wednesday, as the LDP's new policy chief.

Taro Kono, who lost to Kishida in the runoff vote, will be the LDP's public relations head, while former Olympic minister Toshiaki Endo will become the party's election strategy chief, the sources said.
