Actually also very puzzled by that move. Since TCJ already made a blunder with the mic, should just let him resign and leave.

Then keep the WP thingy for a GE play. 

Unless TCJ didn't want to leave and LHL felt that TCJ is no longer useful and can be a lot of trouble ahead or may even turn opposition. So he KO his political and public facing future altogether.

Politics very dark one lah.

very simple.
it happened with Michael Palmer/David Ong when their family members complained to PAP.

It is either someone from TCJ or Cheng side knew that LHL knew about the affair and complained to PAP.
LHL has no choice but to reveal everything and at the same time, someone pulled WP in.

not dark same as corporate politics.
