Thiruvananthapuram, May 12 -- The Congress high command has called former Kerala Pradesh Congress Committee (KPCC) presidents to New Delhi for discussions on Tuesday, as uncertainty over the next chief minister continued in the southern state a week after the assembly poll results were announced. Former Congress Kerala chiefs K Muraleedharan and VM Sudheeran confirmed they would travel to the national capital at the direction of the high command. "It was a surprise when they (AICC) called me. I have booked a flight to Delhi tomorrow. I assume, I will be asked about the state's current political atmosphere. I will give clear answers to the questions they ask me," said Sudheeran, who served as state party chief during 2014 to 2017. The development comes as the Congress top leadership has failed to decide on a chief ministerial nominee a week after the party-led United Democratic Front (UDF) swept the April 9 Kerala assembly polls, winning 102 of the state's 140 seats. Since the results were announced on May 4, hectic lobbying has been underway by the camps of three top contenders for the CM's post - VD Satheesan, Ramesh Chennithala and KC Venugopal. Muraleedharan, who won the recent polls from Vattiyoorkavu constituency, said the decision on the CM's post is expected within the next 48 hours. "When the two AICC observers came to Kerala last week, I relayed my opinion. I will stick to the same opinion. I don't know what they (AICC) will ask. Whatever the high command decides, all the leaders are bound to accept it," Muraleedharan, who served as the state party chief from 2001 to 2004, told reporters. Meanwhile, the IUML, a key constituent of the UDF, expressed strong displeasure over the delay in picking the CM. Party leader P Abdul Hameed told reporters: "If it is prolonged further, there will be repercussions. We hope the AICC leadership realises this."...
