AIZAWL, August 26: After having failed to forge an electoral alliance with the Congress, the Mizo National Front (Nationalist) today decided to contest the lone Lok Sabha seat in Mizoram on its own, party leader Landuhawma said. The party has, however, invited all "like-minded" parties to support its candidate which would be announced soon. The MNF(N) was formed in 1997 by a breakaway group of the MNF led by present chief minister Zoramthanga following the defeat of Lalduhawma in the party organisational election. Lalduhawma, a former Indian Police Service (IPS) officer, was a security officer of late Prime minister Indira Gandhi. He left the service and joined the Congress in 1984 and was elected unopposed to the Lok Sabha the same year. He left the Congress after differences with the then chief minister Lalthanhawla in 1986.
