Barring stray incidents of violence, the 12-hour state-wide shutdown called by CPI-M-led LDF demanding resignation of Chief Minister Oommen Chandy on solar scam issue disrupted normal life and ended more or less peacefully, as a defiant Chandy ruled out his stepping down. Police said no major untoward incident was reported from any part of the state in connection with the dawn-to-dusk hartal. With political slugfest over the solar scam continuing, Oommen Chandy's son shot off a legal notice to a BJP state functionary for making "defamatory" statements, as leaders of congress and LDF opposition in Kerala traded charges at each other. Sticking to its demand for resignation of Chief Minister Oommen Chandy over the solar scam, CPI(M) in Kerala rejected his proposal to set up a joint panel to examine the CCTV footage of the CM's office.
