Umno is trying to turn the government's failure to pass a bill on the Security Offences (Special Measures) Act (Sosma) against Pakatan Harapan, claiming the latter had violated its deal with Putrajaya.

However, opposition MPs are hitting back by pointing out that key Umno leaders Ahmad Zahid Hamidi and Najib Abdul Razak were both absent from the Dewan Rakyat yesterday.

Lembah Pantai MP Fahmi Fadzil said Umno secretary-general Ahmad Maslan was also absent from the vote.

Asked whether Umno could have possibly sabotaged yesterday's vote, Fahmi told Malaysiakini that it was "highly irregular" that 31 government MPs were missing yesterday.
