Found it - Now I understand why no one wanted to provide the link.
Here is the link, Yes he did not apologise but you should read this again to see what an insincere chap that this guy is.

Firstly - what a condescending chap. Read this
"to fellow Singaporeans who like myself voted for the PAP in the last GE, this is my message to you. Just as Dr Teo Ho Pin will not receive my vote in the next GE, let's vote in solidarity to deny the PAP."
Seems like he is suggesting that others persuaded Singaporeans to vote for the opposition while they voted for PAP. Can't recall any other idiot that did this other than Yaw.
Secondly - what a egoistic individual. Read this
"as one of the leaders in Singapore's political opposition, I ought to have weighed the considerations heavily prior to the revelation of my vote,"
When did he become one of the leaders of Singapore political opposition.
