As Singapore is not an Islamic country, and has strong relations with Israel, I would say absolutely no problems at all.

thanks for that Travelling Sam. I didn't really think there would be a problem, but someone else raised the question with me which is what put the element of doubt in my mind. Would have hated getting to the border control and then being refused entry!

Speak to the Singapore Embassy - the only way to be 100% sure. Whoever told you might just have presumed Singapore is an Islamic country as it borders Malaysia and Indonesia?

Finally heard from TA who confirms there is no problem entering Singapore with an Israeli stamp in the passport.
