Speaker of Parliament Tan Chuan-Jin and Tampines GRC MP Cheng Li Hui have resigned from both parliament and the PAP for having an affair, ..and continuing the relationship despite being counselled by Prime Minister Lee Hsien Loong.

This was revealed by Mr Lee at a press conference today - after the PMO had announced Mr Tan and Ms Cheng’s resignations earlier without elaborating on why they did so.  

PM Lee said he spoke to both MPs in February and counselled them. Both agreed to stop their affair.

Mr Tan had also offered to resign, which Mr Lee accepted.

But Mr Lee said he held back on Mr Tan’s resignation to make sure his Kembangan-Chai Chee residents in Marine Parade GRC would be taken care of when he leaves.

However, Mr Lee said he then came across information in July that “strongly suggested” that the relationship was still going on.

That was when he decided that Mr Tan had to go.
