ZPM emerged victorious in the assembly polls on Monday, bagging 27 of the total 40 seats.
Lalduhoma, an ex-IPS officer who had served as the security in charge of former prime minister Indira Gandhi, held a meeting with the newly elected party candidates on Tuesday evening and discussed about formation of the council of ministers and distribution of portfolios, a party leader said.
The ZPM swept the state assembly polls, dethroning the incumbent Mizo National Front (MNF) which got only 10 seats.
The BJP trailed far behind with just two seats and the Congress just one.
