Stung by the leakage of the Central Bureau of Investigation's report into the March 14 Nandigram violence, West Bengal Chief Minister Buddhadeb Bhattacharya on Thursday said that the state government could take up the issue with the Centre.

"We may think of taking it up with the Centre," he said when asked about the reports quoting the CBI findings.

Bhattacharya is presently in New Delhi to attend the Communist Party of India � Marxist Central Committee meeting, which began on Thursday.

CPI-M politburo member Sitaram Yechury termed it, "a clear case of selective leakage".

He, however, refused to elaborate, saying, "The matter is sub judice and it is wrong to preempt anything."

Asked if he had doubts about any political party playing a role in the leakage of the CBI report, Yechury said, "It is for the media to interpret."

According to reports, the CBI report submitted to the Calcutta High Court had concluded that the CPI-M cadres in police uniform were involved in the firing in Nandigram [Images].

The CPI-M politburo met in the morning ahead of the meeting of the Central Committee, which is slated to finalise a draft political resolution to be adopted at the party Congress scheduled in March-April next year in Coimbatore.

After the draft is finalised, it would be debated by all party units across the country where members are free to suggest amendments and recommend deletion or addition of portions. The resolution, once adopted by the party Congress, would guide the CPI-M's future course of action in the long and short term.
