Mr Chandy being kept out of the main list of special invitees alongside Prime Minister Narendra Modi raised eyebrows, as it was during his tenure 2011-2016 that practically every aspect of the metro, including the inking of the agreement, commencement of the work and the trial run was completed.
Mr Chandy, however, kept mum about his exclusion from the main list of special invitees. Though he was given an invite to be seated among the audience, he did not attend the event.
The Congress is planning to make the Kochi metro ride a major event.
