New Delhi: Both the Centre and the non-Congress ruled state governments seems to be at loggerheads over the issue of federal structure in the meeting of chief ministers to discuss internal security of the country.

After facing wrath over the National Counter Terrorism Centre (NCTC) issue, the Centre is likely to draw criticism over its policies to tackle Naxal menace in the country.

The internal security will be reviewed on Monday in the meeting convened by Prime Minister Manmohan Singh.

As per the Home Ministry sources, several issues including Naxal violence, effective counter-terrorist measures, strengthening the intelligence system and police reforms, coast guard and the issues of centre-state relation will be agenda of the meeting.

Interestingly, Odisha Chief Minister Naveen Patnaik and his Tamil Nadu counterpart Jayalalithaa, who had raised voice against the Centre over the NCTC, will participate in the meeting.

However a separate meeting will also be held on May 5 in which West Bengal CM Mamata Banerjee is likely to participate.

A separate session will be held to discuss with chief ministers of naxal-hit nine states. Naxal violence is still posing threat to the internal security of the nation. As per the data of Home Ministry, 600 people were killed in Naxal violence in 2011.
