Prime minister Fumio Kishida warns violence will not be tolerated in defiant speech after the murder of former leader

Many Japanese voters will go to the polls on Sunday with a heavy heart, but also with a sense of quiet defiance, as they cast their ballots just two days after Shinzo Abe, the country’s most influential politician of modern times, was shot dead while making a campaign speech.

As the country struggled to come to terms with the first assassination of a current or former leader for almost 90 years, officials in the Liberal Democratic party (LDP), which Abe dominated for a decade, insisted his death would not derail the democratic process.
