Karat has made an honest comment that it was a mistake.UPA design was to exploit left"s ideological dilemma at a point when new CPM leadership has come to negotiation table.Prakash Karat is more a commited ideologue than a skillful negotiator in face of a veteran burearocrat -turned politician PM MMS.UPA took that advantage.For a while left was in difficult position, but Karat has quickly bounched back with emergence of third front with an unexpected challenge for UPA and BJP both and covered up the problem of political isolation and dialemma.
