SUNGAI BESAR (THE STAR/ASIA NEWS NETWORK) - Former Malaysian prime minister Mahathir Mohamad will campaign for Pakatan Harapan to garner support for his Citizens' Declaration movement ahead of the Sungai Besar and Kuala Kangsar by-elections on June 18, said a former Umno official.

This was revealed by former Batu Kawan Umno vice-chief Khairuddin Abu Hassan.

"He will surely come down to campaign in Sungai Besar and Kuala Kangsar because it is his principle to deny Barisan Nasional the victory," he said when met with Pakatan Harapan leaders during nomination day in Sungai Besar on Sunday (June 5).

He said that if the opposition pact organised a signature drive for the declaration, "Dr Mahathir will surely come".

He said the movement was arranging a schedule for the former prime minister during the campaigning period for the by-elections.

Pakatan has fielded a candidate from Parti Amanah Negara, Mr Azhar Abdul Syukur, to face Barisan Nasional and former ally Parti Islam SeMalaysia (PAS) in Sungai Besar.

Kuala Kangsar will see a four-way fight between Amanah, PAS, Barisan and an independent candidate.
