Hardik Patel, the 24-year-old face of the Patidar community's campaign for reservation that has locked horns with the ruling BJP in Gujarat, seems to be playing hardball with the Congress over his support to the party for the state elections to be held in December. A day after Congress sources indicated that Mr Patel would share the stage with Congress Vice President Rahul Gandhi during his visit to Surat on November 3, he tweeted that the party must first come out with a clear stand on the reservation issue.
