Here's an interesting bit:
Jack Lam: Dr. Ang - I am actually very curious to know - what is your plan for future? Do you plan to remain active in SDP and contest next election? Care to share?
Ang Yong Guan: Jack, dont worry about my political future for the time being. Let's concentrate on winning PE first!
Doesn't really sound to me like someone who's planning to stick around in SDP for much longer.
However, he strikes me as someone who is too free-spirited to fit into the WP disciplined style.
Which means, of course, that he will probably end up in NSP - the safe haven for people disillusioned with their former parties but WP isn't right for them
