Mahathir on offensive against government
May 1, 06 1:14pm
Former premier Dr Mahathir Mohamad's ferocious attacks on Prime Minister Abdullah Ahmad Badawi's government are undermining the administration and could be aimed at forcing Abdullah's early departure, observers say.
Since stepping down in 2003, Mahathir has launched a number of broadsides against the government, which has been gradually unravelling his vision for the country, particularly megaprojects like the national car.
But his criticisms have become more bitter since Abdullah earlier this month dropped his predecessor's long-cherished plans for a new bridge to Singapore, saying that the city-state was asking for too many concessions.
In a sign of growing impatience over Mahathir's barbs, Foreign Minister Syed Hamid Albar has called on the veteran leader to stop the public bickering with the government, warning it would affect the country's image.
"The disagreements should not be escalated to the extent of creating a situation that gives rise to a perception of a political crisis," said Syed Hamid.
"We have to accept the fact that when there is a change in leadership, the current leadership may act or make a decision different from that of the previous leadership," he added.
Sharp-tongued remarks
Mahathir handed over the reins to his hand-picked successor Abdullah in October 2003 after more than two decades in power, ending his stint as one of Southeast Asia's political strongmen.
Initially accused of pulling the strings behind Abdullah's administration after his retirement, the former premier has since become a vocal critic of its decisions.
While some analysts say dissension from the former leader - especially one so intricately involved in the nation's affairs for so long - is to be expected, Mahathir's sharp-tongued remarks are starting to raise eyebrows.
Changes at troubled car maker Proton, which he nurtured from its inception, and a possible free trade agreement with the United States have provided targets.
At his most acidic, Mahathir has accused Abdullah of being unpatriotic by mulling the sale of sea sand to Singapore as part of now-defunct negotiations for the new bridge.
"That there should be any Malaysian leader willing to entertain this idea, to destroy Malaysian seas to satisfy Singapore, speaks badly of his love for his country," Mahathir said last week.
Opposition leader Lim Guan Eng from the Democratic Action Party said Syed Hamid's comments signalled the "beginning of a new crisis" in Abdullah's ruling Umno.
The bridge plans "may have collapsed, but more damaging is the collapse of the relationship" between the two men, Lim said in a statement.
"The wrangling is feeding the perception that Abdullah is a one-term premier who will merely fill the gap in a transition between Mahathir and his reputed ally Deputy Prime Minister Najib Razak.
One-term prime minister
While mainstream newspapers, many of which are owned by ruling parties, have shied away from the issue, the influential website malaysiakini said Mahathir was actively trying to unseat Abdullah."
"It's all about preserving his vision of economic nationalism," the website's editor-in-chief Steven Gan wrote in a weekend editorial.
"With Mahathir rallying his troops within the party, Abdullah is likely to be a one-term prime minister," he said, adding he expected a leadership challenge after the general election, which could be as early as the end of 2007.
However Shahrir Samad, Parliament's backbench leader and a prominent Umno politician, has denied there are any party splits.
"It is to Abdullah's credit that he has refrained from answering directly to the comments that were made by Mahathir," he told AFP.
If Mahathir is plotting to curtail Abdullah's political career, analysts say they do not expect open defiance from Najib, who would be viewed negatively for undermining Abdullah.
"What can actually lead to problems is the people around those two leaders. They can try to raise the temperature," said political commentator Chandra Muzaffar.
