Allegations over dining expenses risk tarnishing Abe’s legacy and could weaken Yoshihide Suga

Prosecutors in Japan have questioned the former prime minister, Shinzo Abe, over a funding scandal that could harm the country’s current leader, Yoshihide Suga.

Abe, who resigned in August, apparently due to ill health, volunteered for questioning this week as prosecutors sought to build a case against his secretary over unreported political funds.
