VK Sasikala this evening drove up to a prison in Bengaluru where she has been sentenced to four years in prison for corruption in a case that involves J Jayalalithaa, the Chief Minister who died in December and was the leader of Tamil Nadu's ruling party, the AIADMK. A crowd of supporters greeted her convoy to signal they remain loyal to her. The 61-year-old, wearing a brown sari, left Chennai in the morning after stopping to pay tribute at Ms Jayalalithaa's memorial, where, her party said, she took "a mighty vow." It did not elaborate on what she pledged.
