"I did not watch the live telecast of the Prime Minister's press conference three days ago, so I am not in a position to comment on his remarks (on Modi)," he told reporters replying to a volley of questions on the issue.
"I have nothing to say on what the Prime Minister said on the issue," Kumar said.
On his views on qualities for a person aspiring to be the Prime Minister of the country, Kumar maintained his past stand on the issue that a person occupying such constitutional post should be secular, liberal and one who can take all sections of the people along, but he/she should not have rough edges.
On the Prime Minister's press conference, Kumar repeated that it was a farewell affair by Singh, but refused to comment on the speculation doing rounds that the Congress may project its vice-president Rahul Gandhi as its prime ministerial candidate.
"It's an internal matter of a political party," Kumar said.
