On 18 Jan, it was already reported in PAP-controlled media that Patrick Nathan, SMRT chief spokesman, had quit.

It is not known why SMRT has to double confirm the departure of Patrick Nathan 11 days later.  (SMRT confirms departure of corporate communications VP Patrick Nathan)

Patrick will be replaced by former Singapore Tourism Board – a stat board – director Margaret Teo who was employed by SMRT in 2014.

PAP has a policy of rotating employees of GLCs, stat boards and ministries.  Very few of these employees venture out into the real private sector after having worked under the yes-Sir! PAP system for more than 1 decade.

Commuters have been expecting bigger heads to roll and this was reported in the Jan 18 article : “The public’s call for change at SMRT has become louder since the latest spate of incidents, ..”.

Instead of firing former paper general CEO Desmond Kuek and the cronies he had brought along to SMRT, the PAP has decided to wayang again by holding Kuek’s subordinate accountable.

If PAP expects this to improve rail reliability, it must be another joke at commuters’ expense. 😦
