KUALA LUMPUR — Mistrust, arrogance and zero communication between each other were among the reasons the Mahathir administration collapsed in rancour and recriminations a week ago, paving the way for Bersatu president Muhyiddin Yassin to take power on Sunday (Mar 1).

He was sworn in as prime minister despite protests of popular support from his predecessor Mahathir Mohamad whose changing stance in a politically tumultuous week killed the Pakatan Harapan government, wiped RM43.4 billion (S$14.3 billion) off the local bourse last Monday and pushed the ringgit lower among most currencies.
