Working with Pakatan can never be justified
Salleh Said Keruak
Mukhriz Mahathir must be very naïve not to be able to tell the difference between the implications of working with Umno leaders and the implications of working with Pakatan Harapan leaders.
If you work with Umno leaders, and if it is with the purpose of changing the party leadership, then this is done during the party election. However, if you work with Pakatan leaders, then it is with the purpose of changing the ruling party during the general election.
This action can only be construed as an act of betrayal to the party considering that the general election is going to come before the party election. Mukhriz must surely know the consequences of his action.
