Lim Kit Siang believes there is nothing seditious about his son and Penang Chief Minister Lim Guan Eng rendering an anti-GST song with children during the launch of free tuition classes.

"I have not seen the content (of the video). But as far as I know, I don't think there's anything seditious. Is there anything seditious?" he replied when quizzed on the matter.

Guan Eng's action had drawn flak from various quarters, with MCA accusing the chief minister of indoctrinating children. A video recording of the incident has since gone viral on social media.

Yesterday, the police said it was investigating the matter and would record a statement from Guan Eng soon.

Asked if he felt it was wrong for his son to do so, Kit Siang replied: "I think there can be an argument whether the CM should be singing."

However, the DAP veteran accused the authorities of turning a blind eye to graver issues.

"I think there are greater crimes in the country and greater offences in the country which have been overlooked.

"I think that is the greatest crime, to overlook great crimes and to go for this sort of things. Please print that," he said.

Kit Siang was speaking at a press conference at the Parliament lobby this afternoon.

Guan Eng, on the other hand, claimed that it was a case of double standard.

"The double standard continues with ferocious attacks by BN ministers against me for dancing along to a song mocking the GST at an event attended by children at a Penang state government free tuition class held in a low-cost flat area.

"Whilst there may be differing views on whether this is appropriate, I must stress that this is not in a school as alleged by BN leaders, but in a low-cost flat and on a weekend," he said.

Lim accused BN of using schools to promote Umno, citing Federal Territories Minister Tengku Adnan Tengku Mansor's visit to SK Putrajaya Presint 14(1) last October as an example.
