Tanzania's ruling party is expected to prevail in presidential and parliamentary elections on Sunday, Reuters reported. In power for more than half a century, the ruling CCM party faces growing pressure to speed up development of Tanzania's significant natural gas resources to spur economic growth and lower stubbornly high poverty rates. Voters seeking to cast their ballot had begun massing at some polling stations at 5 a.m., before dawn broke. High turnout was reported in several areas, and queues snaked around corners amid complaints of long delays. Some 22.75 million people are registered to vote in the East African nation of more than 47 million. Around 57 percent of registered voters are aged 35 or younger. The polls were due to close at 1300 GMT.
