Congress MP Shashi Tharoor has joined a meeting of Congress dissidents in Delhi on the recent setback in state elections. The Congress G-23 or group of dissident leaders are meeting at Ghulam Nabi Azad's home amid calls for organisational changes. Mr Tharoor, so far who has been seen as a fence-sitter on the matter, seems to have taken a side. "I have learned so much from my mistakes, I'm thinking of making a few more," Mr Tharoor said in a cryptic tweet.
