The Kerala High Court on Tuesday sought response of Chief Minister Pinarayi Vijayan on Congress MLA Mathew Kuzhalnadan's plea for a probe against the Chief Minister over the alleged financial transactions between his daughter's now defunct IT firm and a private mining company. Besides the Chief Minister, Justice K Babu also issued notice to Mr Vijayan's daughter, her defunct firm and the mining company, seeking their stand on the MLA's revision petition. Mr Kuzhalnadan moved the high court after a vigilance court rejected his plea for an investigation against Mr Vijayan over the alleged financial transactions between the private mining company and the IT firm of his daughter, T Veena.
