KUWAIT CITY - Kuwait will hold its most inclusive elections in a decade Thursday with some opposition groups ending a boycott after the oil-rich country’s royal rulers pledged not to interfere with parliament. The polls are the sixth in 10 years, reflecting the repeated political crises that have gripped the only Gulf Arab state with a fully elected parliament. The elections come after Crown Prince Sheikh Meshal al-Ahmad al-Jaber Al-Sabah announced the dissolution of parliament in June following disputes between lawmakers and the government, the fourth to be named in two years. Several opposition MPs had been on strike in protest at delays to parliamentary sessions and the failure to form a new government. A core source of friction is MPs’ demand for ministers from the royal family to be held accountable for corruption.
