The main opposition Democratic Party of Japan aims to prevent Prime Minister Shinzo Abe's Liberal Democratic Party from securing a majority in the Dec. 14 Lower House election, DPJ leader Banri Kaieda said Sunday.
The party, ousted from power in the 2012 election, will campaign on a platform raising middle-class incomes through the stabilization of employment, Kaieda said in an interview.
The DPJ will also call for policy measures to support people who work while raising children, he said.
