Parti Pribumi Bersatu Malaysia's (Bersatu) one-month ultimatum for PAS to forge an electoral pact was firm, said the party's chairperson Dr Mahathir Mohamad.

"We have tried to resolve (the deadlock). We have been very patient. We did not say anything bad about PAS. We have done everything possible, what else can we do?

"I don't want to crawl and kiss the feet of PAS leaders," Mahathir told reporters in Putrajaya today.
