In an email to media houses, ULFA anti-talk faction assistant information and publicity secretary Arunudoy Asom said that in case of failure to comply with the deadline, the outfit would be forced to change its leadership.
"The ULFA as a whole is very humbly requesting our chairman to return within three months of issuance of this call to lead the organisation breaking free of Indian control", the statement said.
It further added: "Otherwise, the vacant Chair will have to be filled up by the constitutional process empowering the office bearers and members of the unbound (anti-talk faction) ULFA to change its leadership at the end of the above deadline".
Asom said the ULFA constitution "has not given any one, from chairman down to ordinary members, any power to compromise with the ideals of the organisation".
Asom said that during his underground days, Rajkhowa was adamant on the question of 'sovereignty'.
"But after being in prison, curiously he stopped insisting on the sovereignty issue... His words seem to carry a different meaning to the stand of the organisation", said the statement issued by the outfit's elusive c-in-c Paresh Baruah-led faction.
