Senior civil servant Ng Wai Choong will announce the results of the upcoming polls after the last ballot is cast and all votes are counted.
The Energy Market Authority (EMA) chief executive was appointed Returning Officer by Prime Minister Lee Hsien Loong in April 2013, soon after People's
Association chief executive Yam Ah Mee left for the private sector.
Mr Yam, now managing director at Sembcorp Design and Construction, became an overnight celebrity for his deadpan delivery of the 2011 election results.
Mr Ng, 49, was deputy secretary for policy at the
Ministry of Finance before he was appointed to helm the EMA.
As Returning Officer, he will supervise elections in Singapore, including the Sept 11 polls.
Apart from announcing the results, he will also oversee the conduct of the polls and head the army of officials who will run the polling stations and count ballots.
He was the group assistant returning officer in the 2011 General Election, the presidential election in August that same year and the Hougang and Punggol East by-elections.
