PKR's Kapar MP Abdullah Sani Abdul Hamid sees a possible tie-up between Pakatan Harapan and Umno in the near future.
He said this was something to consider, if and when Umno quits Perikatan Nasional.
"When Parliament reconvenes, the next step is to seek legitimacy" Abdullah told Malaysiakini.
He said they could either be part of the same government or work out a confidence and supply arrangement, like in Perak.
