Penang chief minister Lim Guan Eng went on a brief tirade against the goods and services tax (GST) yesterday, calling it 'celaka' (damned) several times.

"Celaka GST, celaka GST," Lim said at the start of his rant at a DAP fundraising dinner in Kuala Lumpur last night.

The DAP secretary-general joked that Seri Delima assemblyperson RSN Rayer's sedition acquittal for saying 'celaka' gave him licence to use the word.
