To a question on whether Left Front, which supported the UPA I government from outside is a natural ally of the Congress, Singh said, "We had very good experience for the first four years of working with the Left in UPA I but unfortunately Left made a big issue of the nuclear bill" and withdrew support to the government.
"My own perception is that with Left, we know the parameters in which we work together. It is easier to work with the Left because we know the parameters in which they work, " he said.
About the political fallout of the JD(U) walking out NDA in Bihar and whether it can be a part of UPA, Singh said this is an issue which has to be considered by the Congress high command.
"Nitish Kumar did not resign when there was an accident in Godhra and he was railway minister though Ram Vilas Paswan had resigned. Now he (Kumar) has taken a positive step, which is of course a very bold step, which we are appreciating.
"My own view is if he had shown this courage in the last Bihar election, the BJP would not have got so many seats and BJP would have landed in the same position as in Odisha where Naveen Patnaik asked them to leave the coalition," he said.
