Malaysia's political outlook has been clouded since elections in March when surprisingly big gains by the opposition sparked fears of a sudden change in the government and policy.
"It's very important that the political situation settles down," said top banker Nazir Razak, who is Najib's younger brother. "I am sorry but I disagree with the DPM (Najib) when he said that international investor confidence is not affected."
Malaysia's main stock index rose 0.8 percent by midsession on Friday. It has lost 12 percent since March.
