THIRUVANANTHAPURAM: Kerala chief minister Pinarayi Vijayan on Wednesday wrote to Prime Minister Narendra Modi seeking his personal intervention to accord sanction for the ambitious semi-high speed rail project of Kerala, which according to Kerala CM is “a milestone in the progress of the state.” Soon after the chief minister shot off the letter, Opposition leader V D Satheeshan questioned the real interest of the state in the project. Even as the state has been facing a slew of environmental problems, the state government which goes ahead with the project, should tell what’s the priority of the government now, he told the media.
