JYOTI Basu, who so very nearly became the 11th Prime Minister of India, is said to have told a colleague that the situation arising out of the CPI(M)'s decision not to participate in any government the Third Front may try and form was the biggest political crisis for the party in the past 30 years. The May 13 decision of the CPI(M)'s Central Committee to opt out of a possible Third Front government has led to a furious debate not only within the party itself but also in the ranks of its allies where the resentment towards the CPI(M) is palpable. And while the cracks are showing in the CPI(M), there are ample signs that an acrimonious inner-party debate has only been delayed till after May 31.
