Addressing a press conference at the BJP headquarters in New Delhi, Jaitley accused the Congress of having a 'grab-all mentality', saying it has misjudged its electoral capacity in these elections.
Earlier, AICC general secretary Rahul Gandhi told reporters that the Congress was confident of forming the next government at the Centre as well as re-winning the support of the Left parties.
"On a lot of concepts we agree with the Left like education and health. There is a lot of meeting ground with the Left. There is absolutely no meeting ground with BJP for what they did in Gujarat and Karnataka and burnt Christians in Orissa," Rahul said at media interaction programme.
Jaitley lambasted Gandhi's statements by saying that he shows political immaturity and lack of ethics.
He added that the Congress was making such statements because it has gone wrong with its pre-poll alliances.
