Permatang Pauh PAS has condemned those who have criticised its leader Omar Hassan for attending a lunch function with Prime Minister Najib Abdul Razak today.

Jamsari Samad, the Permatang Pauh PAS information chief, said criticisms against Omar were being hurled by the PAS' rivals who were "politically immature".

He explained that Omar attended the event because he was invited in his capacity as the Seberang Jaya mosque committee chairperson and the representative of 28 other mosques in Permatang Pauh.
