At the People's Action Party's (PAP) lunchtime rally on Monday afternoon (April 28), Prime Minister Lawrence Wong acknowledged that each opposition party alone may not have enough candidates to form a government. However, he cautioned that when added up, "the numbers are not small".

"Now if opposition parties break through in several constituencies, then even if the PAP were to be returned to govern - it could be with a severely weakened mandate," added PM Wong.

"How am I going to form an effective cabinet losing three or four ministers?"
