Sept 3 (Reuters) - Japanese Prime Minister Yoshihide Suga said on Friday he would step down, setting the stage for a new premier after a one-year tenure marred by an unpopular COVID-19 response and sinking public support. Suga took over after Shinzo Abe resigned last September. Before Abe"s record eight-year tenure, the role of prime minister was a revolving door, with six premiers in as many years. Here is a timeline of some of the key events in Suga"s term: Sept. 14, 2020: Suga wins the Liberal Democratic Party (LDP) leadership election by a landslide, ensuring he will be premier. He promises to continue Abe"s main policies while pursuing reforms, including deregulation and breaking down bureaucratic silos.
