BATU PAHAT: Umno's cooperation with Parti Keadilan Rakyat (PKR) within the unity government remains intact despite Tengku Datuk Seri Zafrul Abdul Aziz's resignation from the party, says Datuk Seri Johari Abdul Ghani.
Johari, who is Umno vice-president, said both parties must remain united in their efforts to ensure the country's political stability.
