The LDF government in Kerala does not pass muster in the first 100 days of its office even with "grace marks," said Congress leader Ramesh Chennithala in Thiruvananthapuram on Thursday.

Speaking to reporters in Thiruvananthapuram, he said on the 100th day of the government led by Chief Minister Pinarayi Vijayan, even the Left Demoratic Front's (LDF) own leaders are keeping mum. 

Vijayan was sworn-in as the Chief Minister on May 25, completing 100 days in office on Thursday.

"Even Achuthanandan has got nothing to say about the government. No one heard any comments from the CPI, the second biggest party in the ruling LDF, and the LDF Convenor (Vaikom Viswan) is also silent," said Chennithala. 

Asked what he thought about 100 days of the Pinarayi Vijayan government, former Chief Minister V.S. Achuthanandan said, "The time hasn't yet come to make an assessment."

Following the assembly elections earlier this year, Pinarayi pipped Achuthanandan, 92, to the chief minister's chair. 

The veteran Marxist leader was appointed on August 3, 2016, as the Chairman of the Administrative Reforms Commission, a position that comes with cabinet minister's status, but he has not yet taken office. 

"Can someone tell why is Achuthanandan not taking up the post," asked Chennithala, who is Leader of Opposition in the Kerala assembly.

While the whole world is moving towards decentralisation, Vijayan is staying put for "some strange reason", Chennithala said.

"His style of functioning is like dictatorship and he is the master of all and unwilling to delegate," he said. 

Meanwhile, in his address to the people of Kerala on the All India Radio and FM radio channels, Pinarayi thanked them for "fully supporting" him.

"Sustainable development on all fronts is the agenda of my government and another key area is to tackle the menace of substance abuse, especially among the youth. Organic farming is also a top priority on our agenda," said Vijayan in his radio address.
