DMK chief and Tamil Nadu chief minister M Karunanidhi and Prime Minister Manmohan Singh on Monday asserted that ties between the two alliance partners were as strong as ever.
They scoffed at speculations that the 2G spectrum scam probe and raids had brought in strains into the alliance.
The Prime Minister said that the alliance remained strong as ever.
He also told the media that the Karunanidhi had apprised him of the damage caused by the heavy rain that flooded several regions of the state and sought higher compensation for the farmers and villagers who suffered losses.
Karunanidhi called on the Prime Minister in the morning at the Raj Bhawan.
The chief minister also asserted that the relations were strong.
"They are as strong as between you (media) and me", Karunanidhi said perhaps in a jest as he had been maintaining that there was no problem between the alliance partners but it was a section of the media that was working itself up to see a snap in the ties.
It was Karunanidhi's first meeting with the Prime Minister after the probe into 2G spectrum scam by the CBI gathered pace and led to raids on former union telecom minister A Raja and people close to him in the DMK.
Tamil Maiyyam, a NGO in which Karunanidhi's daughter and Rajya Sabha MP M Kanomozhi is a director, was also raided.
The DMK launched campaign in support of Raja across the state.
The chief minister's unhappiness was evident in what is being seen as a snub after he did not receive Singh at the airport or call on him after his arrival on Sunday evening.
Karunanidhi, instead, chose to attend a book release function and cited this as a reason for not visiting the Prime Minister.
The chief minister maintained that he had prior engagement and denied his decision had anything to do with the postponement of the Adyar Poonga inaugural.
It could not be inaugurated as the project failed to get the mandatory environmental clearance from the union government on time.
DMK leaders, including Karunanidhi and Raja, have maintained that the raids or investigations were routine in nature and that Raja would emerge clean as he is innocent and had done no wrong.
