SPP is chiamily party. Chairman Sin is total out of the husband and wife's loop. SPP is individuality party. Look at how Desmond Lim was kicked out of SPP and SDA without any CEC involvement.
We now know Desmond is right about his concerns regarding RP joining SDA. What Desmond has done wrong is getting himself into the way of the chiams. The chiams are as autocratic as the Lees!
