I do not know Lim and never met him.
No interest, no bias.
But I agree with you that since the PAP has always claimed that they are upright, honest and serve with integrity, they did not disclose Lim's ECA (which may be one of the reasons that he had to step down).
Assuming that the other party is a very attractive and alluring lady as well as desirable, then there is a reason for his succumbing to his weakness. For his high position and as a senior executive with NTUC, he definitely should not have any ECA with his staff member or any one working for or affiliated with the NTUC.
If the other party is not exceptionally good looking and young (say over 21 but not over 40), then why even bother to have ECA with her.
But, we are not in his position, and therefore can only discuss and make allegations as a bystander.
As a PAP Minister, his ECA is inappropriate and unacceptable. His conduct is unbecoming of an MP, Minister and Sec Gen of NTUC.
If he has retired from Parliament and NTUC, and any lady wishes to be involved with him, then it is his personal matter, that only his wife and parish priest may deal with it.
