Both Mr Perera and Ms Seah are married.
Mr Perera, who turns 53 this year, has two children. Ms Seah, 36, had her second child in April last year.
The pair sat on the WP’s central executive committee. Mr Perera headed the media team while Ms Seah was the youth wing president.
Mr Perera first emerged onto Singapore’s political scene when he ran as a candidate for East Coast during the 2015 general election. He subsequently became a Non-Constituency MP, before joining the WP’s winning slate for its Aljunied stronghold at the 2020 polls.
Prior to politics, he was a civil servant and later co-founder and chief executive officer of a business research and consulting agency.
Ms Seah joined the WP in 2015, contesting in East Coast GRC at the 2020 polls, after earlier stints with the Reform Party and National Solidarity Party. She shot to online fame as the youngest female candidate at the 2011 General Election, when she was 24.
Ms Seah was last reported in 2020 to be working at a multinational marketing firm.
In 2012, the WP expelled then-Hougang MP Yaw Shin Leong following rumours of an extramarital affair. The incident resurfaced in 2021 when the party refuted claims by Mr Yaw that he was told to stay silent after the alleged affair.
On Monday, former Speaker of Parliament Tan Chuan-Jin – who had been MP for Marine Parade GRC since 2011 – resigned from parliament and the ruling People’s Action Party.
He had been having an affair with fellow PAP MP Cheng Li Hui, who also resigned from the party.
