Kalmadi, an accused in Games-related graft case, is out on bail after spending almost a year in Tihar Jail.
"It is unfortunate... As a sports minister I would just try to ensure that he will not be part of the Indian delegation. This I can ensure that Mr. Kalmadi won't be part of Indian delegation," Maken said.
Apart from the minister, Clean Sports India, a movement for corruption-free sports, also denounced Kalmadi while IOA acting president V K Malhotra sought to steer clear of the controversy, saying he was not part of the its delegation.
Maken's response came after Special CBI Judge Talwant Singh allowed Kalmadi's plea to visit London from July 26 to August 13, while ordering him to furnish a bond of Rs 10 lakh and a surety of the same amount.
"It is unfortunate. The person who has not yet been cleared on charges of corruption is going to London Olympics. Olympics is not just about winning medals, Olympics is also about ethics and morality.
"And as far ethics and morality are concerned, who, as sports administrator, has been accused by CBI and has been in jail, and who has just been out on bail on corruption charges is something which is very baffling and a surprise for me and I am very saddened to see that he has decided to attend the Olympics," Maken told reporters.
