The chief spokesperson for SMRT, Mr Patrick Nathan, has resigned amid talk of leadership changes in the embattled transport operator, following a recent string of high-profile incidents. Several high-profile incidents in the past year, including a tunnel flooding at Bishan and a train collision at Joo Koon, have put Mr Nathan in the hot seat. Commuters have also taken the rail operator to task for not providing timely information during major incidents and multiple train breakdowns. For example, it took SMRT some three hours to publish its first joint statement with the Land Transport Authority (LTA) after the Joo Koon collision last November.
