Talks among various quarters on a national consensus to save Malaysia will be held soon, Opposition Leader Dr Wan Azizah Wan Ismail said today.

"Soon, I will meet with leaders from Pakatan Harapan and other parties, NGOs, as well as individuals, to discuss a core programme that can serve as mutual reference on this national consensus," Wan Azizah said in a statement.

Welcoming a change of stance by some Umno-BN leaders, she said there also needs to be institutional reforms.

This was in reference to a statement made by suspended Umno deputy president Muhyiddin Yassin.

After his suspension, Muhyiddin said it was not enough to just get rid of Prime Minister Najib Abdul Razak, but institutional reforms also need to be done.

This change of stance was followed not long after by another surprise turn in Umno's internal struggles, when former prime minister Dr Mahathir Mohamad quit Umno yesterday.

Mahathir said Umno was no longer a party meant to serve the country, but was instead a party meant to protect Najib.

He then called for a core group to coordinate efforts to oust the prime minister.

Mahathir said this after a private meeting with some opposition leaders, including PKR vice-president Tian Chua and Amanah representatives, at which they mutually agreed that Najib had to go.
