A war of words has erupted between an Umno leader and an MCA leader over the future of the latter’s party in BN, with the spat touching on a royal addendum order related to former premier Najib Abdul Razak’s house arrest.

In a Facebook post, former MCA vice-president Ti Lian Ker targeted Umno supreme council member Puad Zarkashi with historical repercussions of non-compliance with the order, which could see Najib freed from prison.
