"PAS chief tells allies: Don't sideline us"
For the PAS to make such a public appeal indicates that the PR coalition needs to improve its lines of communications. For one PAS could have informed its partners that it was going to hold talks with UMNO on Islamic matters.
To earn trust, one has practise good principles of honesty, integrity and responsibility. Holding secret meetings is not going to earn anyone's trust.
A council of state leaders as suggested would be good to learn and progress together but I would suggest that PAS should not try to impose its religious convictions on the other parties but adopt universal principles of good governance.
I would also suggest that some states could work together to set up a central purchasing department and get more competitive bids for common items.
