A parliamentary election on Friday could produce Morocco's most representative government to date after King Mohammed responded to Arab Spring uprisings by giving up some of his powers, but many Moroccans doubt the vote will bring profound change.

The election will be closely watched as a test case for the ability of Arab monarchies to craft gradual reforms that satisfy demands for greater democracy without revolts of the kinds seen in Tunisia, Libya, Egypt and Syria.

In contrast to previous elections when the result was clear in advance, Friday's vote is a closely-run contest between a moderate Islamist opposition party and a new coalition of liberals with close ties to the royal palace.

Under constitutional reforms backed by the king earlier this year, the new government that will emerge from the election will have more powers than ever before, though the king still has the final say on issues of defence, security and religion.

But the move towards greater democracy could falter if polling day is marred by the kinds of vote-buying that has happened in the past, and if afterwards there are signs that palace officials are trying to meddle in the new government.

It's crunch-time, really: a choice between the old style regime or some change, said Lise Storm, a senior Middle East lecturer at Britain's Exeter University.

The rulers know they cannot continue to run public affairs the way they had been doing in the past.

EVOLUTION, NOT REVOLUTION

Morocco's leaders -- and their Western allies -- say the country is a model for the Middle East that offers a positive alternative to the convulsions of the Arab Spring.

Since succeeding his father to the throne in 1999, King Mohammed has won international praise for improving human rights.

When demonstrations, inspired by the Arab Spring, broke out earlier this year, he responded deftly by backing constitutional reforms that took much of the momentum out of the protest movement.

But there remains a vocal minority who say the king's reforms do not go far enough. Thousands of people joined protests in several cities at the weekend to back calls for a boycott of the election.

The bigger concern for the palace is not the boycott but that apathy among ordinary Moroccans will produce a low turnout, taking the shine off what is being portrayed as a showcase for democracy.

Away from Morocco's political classes, many people struggle to see how this election represents anything new, especially as the main players have all been on the scene for years and are a part of the establishment.

This election will be no different from the others, nothing has changed, said Redouan, a 21-year-old man in a working class district of the capital, Rabat. Same faces, same names. Same political parties.

The monarch has said he wants elections that are free, fair and competitive. But there are already signs the murky electoral practices of the past are still in play.

Money is what moves voter turnout in Morocco, said Ali Anozla, editor of independent news portal Lakome.com.

The bulk of the candidates running in these elections are prominent land owners and businessmen and we are already hearing once again of massive use of money in these polls, he added.

CLOSE CONTEST

Under this year's constitutional reforms, the king will choose the next prime minister from the party that wins the biggest share of the vote. It is already clear Abbas Al Fassi, who holds the job now, will be replaced because his Istiqlal party is widely unpopular.

The moderate Islamists of the Justice and Development Party (PJD), say they believe they can take the largest share of seats. They hope to replicate the success of moderate Islamists in Tunisia who won an election last month.

Their principal challenger is the Coalition for Democracy, an alliance of eight parties that was formed in October.

The bloc is led by the finance minister in the outgoing government but many analysts say its principal power-broker is a friend of the king who used to hold a senior interior ministry post before founding a political party.

With opinion polls banned in Morocco in the 15 days before polling day, it is not clear which of them will win. Analysts say it is too close to call.

Whichever bloc emerges with the most seats in parliament, they are unlikely to be able to form a government on their own. That will force them to seek an alliance, and possibly even a grand coalition between the Islamists and the liberal bloc.

That worries economists, who want to see a cohesive government able to narrow the budget deficit, reduce the 30-percent-plus youth unemployment rate and address the needs of the 8.5 million Moroccans below the poverty line.

What we want to see is a strong government, said Liz Martins, a senior Middle East economist at HSBC.

Our concern is that Morocco ends up with a divided parliament and a not so-homogenous government that will not be able to get anything done. That would be a danger.
