PKR secretary-general Saifuddin Nasution today accused four ex-PKR MPs-turned-independent, particularly Zahrain Hashim (Bayan Baru), of being BN's 'attack dogs'.

"They are being used as attack dogs, hired mercenaries," said Saifuddin, during a press conference at the Parliament lobby.

He said independent MPs are now BN's newest platform to attack Pakatan Rakyat because there too few BN MPs capable of going toe-to-toe with the opposition.
