Admitting that there could be differences of opinion among UPA leaders on the Naxal issue, Prime Minister Manmohan Singh said on Friday that the Centre will work with all state governments regardless of their "political complexion" for enforcing law and order.

"We are a functioning democracy and also there are occasions when there are differences of opinion among various leaders of our own coalition," he said, when asked about Centre's readiness to work with Left Front-ruled West Bengal in fighting the Maoists. The Prime Minister was speaking at a summit in New Delhi.

"Let there be no doubt, law and order as I said, is the primary responsibility of every civilised state and whatever comes in the way of maintenance of law and order will be dealt with as it ought to be dealt with", Singh said.

The Prime Minister said the Centre needed active cooperation from states for maintaining law and order and was willing to work with all the state governments "regardless of their political complexion to strengthen the processes of enforcement of law and order".
