Speaking at a function to mark the foundation stone laying ceremony of the Rs 5000 crore Kochi Metro project, Antony said he was "saddened" that CPI(M) veteran V S Achutanandan did not attend the function.
"I am sad that he did not come. There should be no politics in developmental activities," he said.
Antony said Achutanandan had done lot of work for the Kochi Metro project when he was Chief Minister.
LDF had yesterday boycotted the three day 'Emerging Kerala' meet of the state government holding that it was a platform to sell natural resources, including land, to private investors.
Development projects were like "relay races", Antony said.
The Kochi Metro project was conceived when Antony was chief minister.
After four governments came and went, this project has now become a reality, he said.
