Armenians will elect a new Parliament today in a closely fought race between the ruling party and a former coalition partner that heralds the start of a parliamentary system of government. <br/><br/>Under controversial constitutional reforms, parliament, rather than voters, will elect the president for the first time, and the office of Prime Minister will become more powerful, reducing the presidency to a largely ceremonial role. <br/><br/>The opposition says the changes are a ruse to let President Serzh Sarksyan slip into an enhanced Prime Ministerial role at the head of the ruling Republican Party of Armenia (RPA) when his presidential term ends in 2018. Sarksyan, 62, denies the reforms were designed to extend his political career.<br/><br/>The outcome of today's vote was difficult to predict, with polls showing the RPA neck-and-neck with an opposition alliance led by wealthy businessman Gagik Tsarukyan.
