Anwar, who is MP of Permatang Pauh, said that the DAP chairman was disappointed with him for not agreeing with the senior lawyer in filing a suit against the Sultan of Perak over the sacking of the Pakatan government in the state.
Anwar said this to reporters after attending a Pakatan rally in Ipoh last night.
"Our opinions differ on the suit against the sultan. What he said was his personal opinion."
He also dismissed Karpal's allegations that he had caused disarray in Pakatan with his calls for BN elected representatives to defect to Pakatan.
Anwar said he had discussed Karpal's outburst with DAP leader Lim Kit Siang and will be talking to Karpal too. He also said that a Pakatan meeting yesterday did not discuss the matter.
Earlier in the day Karpal attacked Anwar for the disarray Pakatan was in at the moment, especially in Perak.
The rally held at the Perak menteri besar's official residence in Ipoh last night attracted more than 8,000 people. Among the Pakatan leaders present were PAS president Abdul Hadi Awang and DAP leader Tan Seng Giaw.
Kit Siang and DAP secretary-general Lim Guan Eng were conspicuously absent although they were supposed to be at the function.
