"I have not come here with any good news to be conveyed to you people," he said sarcastically in Tamil when he asked to comment on Opposition demands for Raja's resignation over the spectrum issue.
The Chief Minister also dogged the question about bringing up the matter with Prime Minister Manmohan Singh and Congress President Sonia Gandhi.
Talking to reporters at the Tamil Nadu House after a meeting with President Pratibha Patil, during which he invited Patil for inaugural ceremony of the 9th World Tamil Conference, Karunanidhi refused to comment on his son and Union Chemicals and Fertilisers Minister M K Alagiri's prolonged absence from Parliament.
"You ask him," he said.
"Let him first give his opinion. Then I will give mine," he said that when he was pressed further to comment on the matter.
According to sources, he is expected to raise the issue of early passage to the Tamil Nadu Assembly's resolution to revive Legislative Council in the state in the parliament during his meeting with Singh and Gandhi.
In line with the primarily motive for making the two-day visit, Karunanidhi will meet Planning Commission Deputy Chairman Montek Singh Ahluwalia to finalise Tamil Nadu's annual plan outlay on Monday, May 3.
During his meeting with Ahluwahlia, the DMK chief is likely to ask for more allocation of fund for Tamil Nadu.
