AMMAN (Reuters) - Jordan holds parliamentary elections on Tuesday that the powerful Muslim Brotherhood will boycott in protest at what it says has been a gradual erosion of parliaments independence. The Brotherhood boycott, coupled with apathy over an assembly seen as increasingly a rubber stamp for government policy, could bring one of the lowest turnouts since parliament was revived in 1989, analysts and politicians say. Many Jordanians will not participate in the elections because of their conviction of the futility of participating... and this has been strengthened by the new electoral law that is not convincing to anyone, Mohammed al-Momani, a political science professor at Yarmouk University, said. The Brotherhood absence has left less than a seventh of the 763 candidates campaigning under party banners, with the field open for tribal candidates mostly loyal to King Abdullah, who appoints the prime minister and his cabinet. Prime Minister Samir al-Rifai has sought to drum up support for the polls and met young people, women and even Muslim imams with one message - participation is a national duty. Those who dont vote are giving up their rights. There are a lot of expectations and we hope the next parliament will be representative of the will and desires of every single Jordanian, Rifai told reporters on Sunday. The ballot comes almost a year after King Abdullah dissolved the last parliament halfway through its term. In the post-election period, Jordan faces the challenge of forging ahead with reforms to spur growth in a sluggish economy hit by the global downturn. A parliament that acquiesces in unpopular policies was needed to give credibility to state decisions even if its policy-making role was almost negligible, independent politicians say. The Muslim Brotherhood, the countrys only real opposition, say they are not turning their back on parliamentary democracy but protesting an electoral law that ensures pro-government loyalists are elected. We are seeking a change in the rules that would bring a parliament that truly represents people, said Sheikh Hamam Said the head of the Brotherhood. , whose political arm, the Islamic Action Front, is the countrys largest party.
