Discussions between leaders of Congress and Kerala Congress (Mani) failed to resolve the differences between them over the proposed merger of Kerala Congress (Joseph) with KC (M).

"Leaders of both the parties agreed to disagree," UDF convenor P P Thankachan, who was part of the discussions, told reporters.

While Congress leaders feel Kerala Congress(M), a UDF constituent, should have held discussions with the front before taking a decision on the merger, KC(M) leaders have held that the merger decision was an internal matter of the constituent and there was no need to discuss it with the UDF.

Thankachan, Opposition leader in the assembly Oommen Chandy, Kerala PCC President Ramesh Chennithala and Kerala Congress(M) leaders -- K M Mani and P C George participated in the discussions.

Leaders of Congress and KC(M), who were meeting for the first time to discuss the merger issue, decided not to air their views publicly on the issue with the media.

Both parties also decided to cooperate wholeheartedly to ensure the success of 'betrayal day' being observed tomorrow by the UDF, protesting against the price rise.

Thankachan said discussions would be held with coalition parties on convening a meeting of the front this month itself.

To a query, he said no discussions were held today on seat sharing.

The two Kerala Congress factions have decided to merge on May 27. Kerala Congress (J) was hitherto with the CPI(M) led Left Democratic Front.
