Gerakan Youth deputy chief Andy Yong has called for BN to set up a fact-finding committee to deal with acts of violence perpetrated by members of the coalition.

Yong said this in reference to Penang Umno causing a ruckus at cartoonist Zulkiflee Anwar Haque's exhibition at Komtar today and supporters of Umno's Pasir Salak MP Tajuddin Abdul Rahman attacking an opposition MP on Parliament grounds yesterday.

"I condemn the recent ruckus in Parliament and at Komtar. Some Umno members are behaving like thugs and this is inappropriate.

"One of the main causes of defeat during last two general elections, or lack of support for (BN) component parties, were due to some of Umno's arrogance and actions," Yong said in a statement today.

He therefore called for this issue to be addressed by the ruling coalition.

"Perhaps BN needs to form a fact-finding committee to solve such acts..." he said.

Yong said the committee should focus on those acting to the detriment of BN component, and that their actions were merely out to promote themselves.

"I believe most of the grassroots leaders, be they from Gerakan, MCA, MIC and the component parties from East Malaysia, want positive actions and changes," he said.

If these recent actions were not addressed, Yong warned, the individuals involved would cause problems that would undermine the BN.

Yesterday, Tajuddin's supporters, including his son Firdaus, tried to attack Shah Alam MP Khalid Samad on Parliament grounds.

Umno secretary-general Tengku Adnan Tengku Mansor in a statement insisted that Umno was not involved in the incident.

In another incident, a group led by Penang Umno Youth chief Rafizal Abdul Rahim thrashed an exhibition of cartoons by Zulkiflee, better known as Zunar, that it claimed were critical of the government.
