Umno information chief Annuar Musa is offering RM10,000 for the best essay or social media posting which can prove DAP veteran Lim Kit Siang is a "racist".

The social media posting or essay should be titled 'LKS is a racist, anti-Islam and a dictator of 51 years, is it true?' he told reporters during a press conference at the Parliament building.

"Work on them and send them in to the Umno information office.

"The reason for the competition would be to encourage people to carry out a research into allegations of Kit Siang being a racist, anti-Islam and a dictator," he said.

The Ketereh MP said this was in response to Kit Siang calling him the "father of racists".
