Jakarta – The ruling Democratic Party has expressed its disapproval of the rally by activists in front of the State Palace on Friday who presented a mock buffalo head to President Susilo Bambang Yudhoyono who was celebrating his 62nd birthday.

"It is not Indonesia's culture to insult our leaders. It's okay to criticize our leader, but please do this with little decorum," said Democratic Party executive board chairman Sutan Bhatoegana as quoted by tribunnews.com on Saturday.

"This insult is against the traditional teachings of our ancestors. We must pay respect to our elders," Sutan said. Sutan believed that Yudhoyono would not be offended by the action.

Several activists were reportedly arrested by the police for taking the mock buffalo head to the palace.

The activists said that they would take a mock buffalo with them to a rally on Saturday. However, they have reportedly canceled the rally. No information is available on the reason for canceling.
