"It is unfortunate. He was Chief Minister, then Governor and after that became External Affairs Minister. He had a dream run in the party," Congress spokesperson Ajay Maken told reporters here.
In a letter to Congress president Sonia Gandhi yesterday, the veteran leader resigned from the primary membership of the party.
Referring to Krishna's faux pas at the UN in 2011, Maken took a dig at him and said "Congress and the government had to face a lot of flak for him as he mixed up his statement and read out a wrong one at the UN."
Taking potshots at Congress leadership a day after his exit from the party, Krishna today said it did not need "mass leaders" but only wanted "managers" as he complained of being sidelined due to his age.
"With pain and anguish, I have decided to quit Congress," he stated, adding that "self-respect" was important for him.
He, however, declined to spell out his next step, saying he would have to think about it.
