New Delhi, May 15 2010: The Centre is unlikely to allow NSCN (I-M) general secretary T Muivah to enter Manipur fearing further escalation of tension.

According to agency reports quoting highly placed sources, the issue was extensively discussed at the recent core committee meeting of the Congress party, which was also attended by Prime Minister Manmohan Singh, Finance Minister Pranab Mukherjee, Union Home Minister P Chidambaram, among others.

Sources said it was decided at the meeting not to allow Muivah to go ahead with his visit because it might trigger further tension and ethnic clashes in Manipur.

The question does not arise, sources said.

The meeting also discussed Union Home Secretary GK Pillai's report and came to the conclusion to focus on restoring the supply lines to Manipur.

Pillai had also tried to persuade Muivah to return to Dimapur, when he called on the Naga leader on Wednesday.

Meanwhile, Bharatiya Janata Party (BJP) made a scathing attack on the Union Home Ministry holding it responsible for the mess in Manipur, demanding withdrawal of permission given to Muivah to visit his hometown.

A delegation of the BJP, comprising Prakash Javedkar, Bijoya Chakravarty and Tarun Vijay, visited the State on Thursday to take stock of the situation in the State.

The delegation upon its return to the National Capital called on Chidambaram to appraise him of their findings.

Briefing newsmen, Javadkar said the crisis in the State was the creation of the Central Government, which unilaterally gave permission to Muivah to visit Manipur, without first consulting the State Government.

Making a direct attack on Union Home Minister, the BJP said Chidambaram has become an expert on creating problems and creation of peace into crisis.

A four-member delegation of Bharatiya Janata Party (BJP) met Home Minister P Chidambaram on Friday to demand that Manipur's territorial integrity be protected.

Party spokesperson Prakash Javadekar, who led the delegation, said: "There is no question of disturbing the territorial integrity of Manipur.

There is no question of anything to do with Manipur as far as the NSCN-IM negotiations are concerned.

So boundaries are not negotiable" .

He also mentioned that they had sought vehicular traffic along national highways (NH-39 and NH-53) should not be obstructed.

"We said that as the supplies situation is precarious, there has to be immediate steps to clear (the economic blockade) and bring the supply through NH-53 .

We also demanded that there are threats issued to non-Manipuris that after May 31 they will not be allowed in Manipur to stay; that should also be taken note of," he said.

"He (Chidambaram) said that he has already made his position clear umpteen times, but we requested him to make it once more." he added Manipur is facing an economic blockade by supporters of NSCN (IM) whose leader Th Muivah has been denied permission to visit his village in the state.

Earlier, violent clashes between Muivah's supporters and security forces at the border town of Mao resulted in the death of two NSCN-IM supporters who tried to snatch weapons from the state force personnel, and left several others injured.
