PRIME Minister Lee Hsien Loong said that 'there is no absolute certainty in any process of choosing people,' when explaining the unprecedented last-minute pullout of unionist Steve Tan from the PAP slate on Nomination Day.
'We're looking for many attributes, strengths and capabilities, and also testing for weaknesses, and there's no process which is 100 per cent accurate.'
'And even if you're accurate now, something may happen later on and we have to revise our assessment,' he said at a press conference after nominations closed on Wednesday.
Mr Tan, 37, told reporters that he had stepped down for 'personal reasons'. MP Baey Yam Kheng replaced him in the Tampines GRC lineup, while new face, surgeon Chia Shih Lu, took Mr Baey's place in Tanjong Pagar GRC.
Mr Lee was unequivocal that party leadership had not known about Mr Tan's past troubles, arguing that the change would not have been at the eleventh hour if they had.
He said that the party and Mr Tan could have 'pretended there was no problem and just carried on'.
'But Steve Tan is honourable, we are (as well), and we decided that awkward as it is, we just had to go through with this and made the last-minute change and explain to people: I'm sorry, something has come up...we have had to make a change.'
Separately, Labour chief Lim Swee Say said Mr Tan was put up as a candidate 'based on our knowledge of his track records over the last 10 years'.
On Mr Tan's decision to drop out of the contest, he said: 'I'm glad he took the decision before the GE. I suppose he came to the decision in the interest of the party, in the interest of the voters. I take consolation that we have responsible people who put the bigger voter interest ahead of personal interest.'
