FACTBOX-Key political risks to watch in Malaysia

KUALA LUMPUR, Aug 7 (Reuters) - Malaysian Prime Minister

Najib Razak could call national elections anytime between now

and April 2013, but he may wait to announce a generous budget on

Sept. 28 as he plays a risky waiting game.

The ruling National Front coalition is widely expected to

win the election but further gains by the opposition after its

strong performance in 2008 could undermine Najib's standing.

Holding back until after September would give Najib more

time to shore up flagging support among ethnic Chinese voters,

and to convince Malaysians that his reform efforts are working

as he tries to reverse the ruling coalition's worst election

showing in 2008.

It would also make him vulnerable to any worsening of the

global economy or the emergence of fresh corruption scandals

that could push swing voters over to the three-party opposition.

The political atmosphere is becoming more tense as the

election looms. Key opposition figures have complained of hate

speech and acts of intimidation directed at

them..

Malaysia's economy grew at an annual pace of 4.7 percent in

the first quarter of the year, the central bank said in May,

slowing from the previous three months but beating market

expectations as firm domestic demand helped offset a slump in

exports. Economic growth is expected to slow to 4-5 percent this

year as exports suffer, the central bank has said.

Following is a summary of key Malaysia risks to watch:

ELECTION APPROACHING

The polls will be a test of Najib's efforts to reform the

state-heavy economy and roll back repressive security laws

without upsetting the status quo that has seen his dominant

United Malays National Organization (UMNO) party rule since

independence in 1957.

The election promises to be the most fiercely fought in

Malaysia's history, and already tensions are high after

opposition leader Anwar Ibrahim was charged over his role in a

major street protest for electoral reform in April.

In addition, senior opposition politician Rafizi Ramli, who

made a series of revelations about alleged government

wrongdoing, was arrested in early August for disclosing bank

details related to a high-profile corruption case involving the

family of a former minister.

Meanwhile, the government is planning a fresh round of cash

handouts to poorer families, Deputy Prime Minister Muhiyuddin

Yassin said in June, a move aimed at shoring up support among

undecided voters.

Najib announced bonuses worth half a month's salary for

civil servants and 500 ringgit ($160) each for government

pensioners would be paid ahead of Eid-Al-Fitr celebrations later

this month.

In July, Najib -- facing growing public demand for greater

political and social freedoms -- said he would scrap the

colonial-era Sedition Act, which has been used over the years to

silence dissent.

Uncertainty over the timing of the vote could harm the

economy as companies hold back on spending, while an overly

generous budget would sharpen concerns over Malaysia's chronic

budget deficit.

Najib's personal approval rating remains high but support

for his ruling coalition continues to slide. According to a June

survey, Najib's approval rating eased one point to 64 percent

while the coalition's popularity fell 6 points to 42 percent.

Two July defections from coalition in what has traditionally

been a safe bank of seats in the east Malaysian state of Sabah

have added to Najib's worries.

What to watch:

- Clues about the timing of the election. Signs that the

global economy is deteriorating more rapidly could prompt Najib

to rush to the polls before Malaysians feel the pain from a

slowdown.

- Large anti-government protests, and the government's

response to them, as well as racial and religious relations.

- Najib is trying to reach out to non-Muslim minorities who

make up about 40 percent of the population. Last year, he set up

diplomatic ties with the Vatican in a bid to win Christian

support.

ECONOMIC REFORM

Najib pledged to reform a decades-old affirmative action

policy favouring ethnic Malays and replace it with a "New

Economic Model" to promote greater competition and boost

domestic investment that has lagged in recent years.

But the prime minister has since softened his stance on

reforming the policy for fear of alienating conservatives among

the majority ethnic Malays who make up about 60 percent of the

electorate. Investors and the opposition complain that the

race-based policy has been widely abused, fostering cronyism.

The government is implementing a $444 billion initiative,

called the Economic Transformation Program, that is aimed at

propelling the country to developed nation status by 2020.

The government says the ETP has helped it turn the corner on

years of sub-par investment, pointing to a 19 percent jump in

private investment last year. Critics say the ETP is overly

reliant on government funding, which could end up putting

further strains on a budget deficit that hit 5.4 percent in

2011.

The central bank has kept its benchmark interest rate on

hold at 3 percent since May 2011, a position it maintained in

July. The government expects the budget gap to fall to 4.7

percent this year but that target could be put at risk by

election spending and a worse-than-expected global slump.

Many analysts believe Najib is waiting until after the

election to announce politically sensitive cuts to fuel

subsidies that he has described as economic "opium". That move,

as well the implementation of a new goods and services tax, is

seen as crucial to tackling the chronic budget deficit and

reducing the government's heavy dependence on the oil sector.

What to watch:

- How the global slowdown affects the Malaysian economy, and

how this affects development spending.

- A possible rise in Malaysia's budget deficit if the economy

slows and the government ramps up spending in an election year.
