UPDATED 12.39PM | with comments from Rafizi Ramli, Zaid Ibrahim

With less than 24 hours to go before Umno and PAS ink a charter to seal their alliance, Pakatan Harapan leaders air their views on the political marriage between the nation's two biggest Malay-Muslim parties.

Lim Kit Siang wondered who would be prime minister if the alliance wins the general election and assigned an epithet for the three potential candidates - "1MDB man" former premier Najib Abdul Razak, "corruption king" Umno president Ahmad Zahid Hamidi and corrupt Muslim leader "supporter" PAS president Abdul Hadi Awang.

"So who is the prime ministerial candidate for the PAS-Umno alliance of klepto-theocracy – Najib again or Hadi or Zahid?

"Or they don’t dare to talk about it and want to continue to mislead the people of Malaysia?" he said in a statement this morning.

Penang Deputy Chief Minister II P Ramasamy, on the other hand, believes the alliance is a “suicide mission” for Umno.

"PAS, as an opportunist and selfish political party, has nothing to lose in this game of thrones.

“What a better way of finishing off Umno than in the entrapment of the political charter before it turns its guns against Harapan.

“For PAS, the charter might be a way to chart its next course of action but, unfortunately for Umno, it might be charter for political suicide," he said in a statement.

Here's what other Harapan leaders are saying:

PKR vice-president Rafizi Ramli

As with the previous Umno-PAS marriage, this marriage will fall apart. Is it just a matter of time because they don't know who is the husband or who is the wife in this marriage.

When their political strategy fails and they fight, they will go back to calling each other kafirs (infidels)

They shout about ummah unity when they are the ones calling other kafirs before this and dividing the ummah.

Harapan leaders are in full throttle poking fun at PAS Umno alliance. Will they last; who is PM? etc. GE long way to go mates; let them be. Try to reduce politicking and see if we can manage the country’s problems first.
