Will Perak trigger a political spillover?

Umno has managed to oust Tan Sri Muhyiddin Yassin’s No. 2 man. Will this have a big effect on Bersatu-Umno ties at national level? Can this be seen as the start of an Umno mutiny against Bersatu/Perikatan Nasional? Is Umno president Datuk Seri Ahmad Zahid Hamidi “at work”? Taking into account Perak is his home state, could Zahid be telling Muhyiddin, “If we can do it in Perak, we can do it in Putrajaya, too”?
