KUALA LUMPUR (Jan 13): Prime Minister Datuk Seri Najib Razak is set to announce the revisions to Budget 2016 on January 28, Treasury secretary-general Tan Sri Mohd Irwan Siregar Abdullah said today.

He said the planned tweaks would not see cuts in the salaries of some two million civil servants.

"The prime minister will announce the revised budget on January 28 ... let’s wait for his announcement to see what the details are," he said at the launch of the World Bank's office in Kuala Lumpur today.

In his speech earlier, Irwan said the revision was necessary due to the drop in oil revenue and the ringgit's lower value.

However, he said the revision would not affect the previously planned projects.

Last week, Najib announced Budget 2016 would be revised to take into account Malaysia's falling revenue from lower oil prices and uncertainties in the global economy.

The national budget tabled last October should be more "realistic" and in line with the current economic situation, he said.

Budget 2016 was tabled when oil was US$48 per barrel. The price has now fallen to below US$33 per barrel.
