The chief minister said the plan document itself was lengthy and encompassed many subjects.
Minister of State for Planning Rajeev Shukla dismissed Jayalalithaa's accusations and said that all chief ministers, including those belonging to the Congress, had been given 10 minutes to speak.
"It is wrong to politicise the matter. The time limit applied to all chief ministers. Where is discrimination," he said.
Shukla said Prime Minister Manmohan Singh had accommodated Jayalalithaa by agreeing to her request to speak early.
He said that the meeting was to last for about seven hours and there were around 35 speakers from states and union territories apart from union ministers and the prime minister.
