Prime Minister Lee Hsien Loong has said that he accepted Speaker of Parliament Michael Palmer's resignation with great sadness but added that all MPs needed to uphold high standards of personal conduct.
Writing on his Facebook page shortly after the shock announcement was made at a press conference, he shared Mr Palmer's letter of resignation as well as his response to it.
In it he praised Mr Palmer for his work as an MP in Pasir Ris-Punggol GRC and Punggol East SMC, and also as Speaker of Parliament.
"As Speaker over the past year, you have presided over proceedings in the House with dignity and a sure touch. You maintained order and decorum during Question Time and debates, struck the right balance of flexibility and firmness in applying the Standing Orders, and won the respect of Ministers and backbenchers alike, " he wrote.
But he stressed that PAP MPs and Grassroots Advisors need to uphold the highest standards of personal conduct, especially in dealings with constituents, grassroots activists and staff, adding that the Party also has to be seen to hold its MPs and Advisors to those standards.
He went on to say: "I am glad that you realise that what you did was wrong, and have been forthright in acknowledging the mistake you made."
He encouraged Mr Palmer to continue contributing to society in his own way.
