PETALING JAYA, Malaysia - As the squabbles in Pakatan Rakyat intensify, more rebels are likely to surface over the next few days.

Wangsa Maju MP Wee Choo Keong may be next in line to face disciplinary action for criticising Penang Chief Minister Lim Guan Eng, joining other Parti Keadilan Rakyat leaders who have been referred to the disciplinary committee for going on the offensive against Pakatan Rakyat comrades.

Selangor Mentri Besar Tan Sri Khalid Ibrahim, meanwhile, challenged disgruntled PKR elected representatives to "go ahead and quit the party".

At the same time, PKR's Kelana Jaya MP Loh Gwo Burne quashed talk that he was leaving the party.
