WP:OVERLINKING is a problem in this article. So far in the lead and career sections there are too many links that might disrupt the prose. Try cutting down on a few obvious links; I think 'Prime Minister' and content from the career section (such as Minister of Health etc) that was already mentioned in the lead could be unlinked.
The third paragraph of the lead could be further elaborated - did he hold all of those positions all at once?
"Balaji Sadasivan was born on 11 July 1955[1] in Singapore, the son of Indian immigrants" - not grammatically great. How about Balaji Sadasivan was born in Singapore on 11 July 1955 and the son of Indian immigrants
There is no actual error, but it is missing a preposition ("to") so I though it would sound better like Balaji Sadasivan was born on 11 July 1955 in Singapore, to the son of Indian immigrants. It doesn't really matter though, the rest of the article is well written. ☠Jaguar☠17:17, 14 December 2014 (UTC)[reply]
Try merging the last two paragraphs in the Later years section
Rename Notes to 'References' and 'References' to Notes... they're the wrong way around
'Done differently Actually, all the "references" were already in the Notes section, so I removed the References section and renamed the Notes section to References. --Hildanknight (talk) 05:11, 13 December 2014 (UTC)[reply]
Sorry this was late. This is a generally well written article and is already close to meeting the GA criteria. Once all of the above have been addressed I think it could pass. I'll put this on hold for the standard seven days. Regards ☠Jaguar☠17:31, 12 December 2014 (UTC)[reply]
Thanks Hildanknight, this is a pretty well written article anyway and now I believe it meets the GA criteria. Bearing in mind it was a short review anyway so it didn't need much clarification! The grammar on that sentence should be fine as I believe it now meets the GA criteria as it is. The references are all fine, I had to check them manually as the toolserver is currently down. Anyway well done on another GA. ☠Jaguar☠17:19, 14 December 2014 (UTC)[reply]
