Former deputy prime minister Wong Kan Seng revealed yesterday that he had thought of retiring from the Cabinet in 2001.
He had been in the government for 17 years and had told then Prime Minister Goh Chok Tong that he was prepared to be let go 'any time'.
But Mr Wong said that Mr Goh decided that he should continue.
The same thing happened with Mr Lee Hsien Loong, who took over as the Prime Minister in 2004, when Mr Wong again made his intention of retiring known to Mr Lee.
Mr Wong, 64, was speaking at the sidelines of the National Clan Associations Congress held at the premises of the Singapore Federation of Chinese Clan Associations in Toa Payoh. He attended the event as its guest of honour and in his capacity as the Deputy Prime Minister, his last official engagement as DPM.
Mr Wong said that he had mixed feelings about retiring, as he had been 'involved in government for so long', but he added that the new Cabinet was a good one, and he believes the members will have the strength and ability to carry through with their plans for Singapore.
