Tokyo, 06 Shawwal,1437 AH, 11 July,2016 , SPA -- Japanese Prime Minister Shinzo Abe's ruling coalition and their allies won a two-thirds majority in upper house elections, paving the way for Abe to amend Japan's pacifist constitution, local media reported Monday, according to dpa. Abe's Liberal Democratic Party (LDP) and its coalition partner Komeito retained a majority in the House of Councillors, with both the LDP and Komeito increasing their seats in the upper chamber of parliament despite the premier's economic measures proving to be ineffective so far. The LDP won 55 seats, Komeito 14, while the main opposition Democratic Party captured 32, final results showed. The Japanese Communist Party, which attracted voters frustrated with Abe's government, won six seats, up from three. Every three years Japan's upper house holds elections for half of its 242 seats. A total of 389 candidates were running for the 121 seats in Sunday's race. The premier needs the support of two-thirds of both chambers of parliament in order to call a national referendum on amending the constitution. The coalition already holds a two-thirds majority in the more powerful lower house. -- SPA 11:34 LOCAL TIME 08:34 GMT www.spa.gov.sa/w
