I suspect that you are thinking along the lines of a normal political party with a firm ideology and political leader chosen by the party.
Its a party leadership that are wholly coopted and actually despise the party except as an electioneering platform. A few morsels are thrown to party porlumpars such as seat for Tin Pei Ling etc. The first sign of trouble and they will claim they are not party members and will readily walk away. LHL does not need to worry about the country and party, he needs to save his own skin and whats left of his credibility.

This is going to be a difficult knot for LHL to unravel. The challenge is that he is up not against his nemesis ( JB Jeyaratnam or Chee Soon Juan ) but it is own blood brother and sister. Even he wins, he still loses because the reputation is smeared by the allegations and the ties with his brother and sister will forever be severed. But he has no other choice but to think for the party and for the country. He, being the PM, has to follow through no matter how now that LHY has countered all his rebuttals and alleged him to be lying under oath in Parliament.
