On 19 July, WP secretary-general Pritam Singh revealed that Perera and Nicole Seah began an affair some time after the 2020 general elections, which had ended before the video surfaced.

During the 2020 general election, Perera joined the five-member Workers' Party team contesting in Aljunied GRC with team members, Pritam Singh, Sylvia Lim, Gerald Giam and Muhamad Faisal Manap[10][11] and they won with 59.95% of the vote, so Perera became an elected Member of Parliament representing the Serangoon ward of Aljunied GRC in the 14th Parliament.

Party leader Pritam Singh told the press that he would have sacked both of them had they not offered their resignations, as they had initially been untruthful when they were first asked about rumours of an affair between them following the 2020 general election.

In 2019, he participated in the debate on the Protection from Online Falsehoods and Manipulation Act (POFMA), highlighting how the proposed tool "is a cure worse than the disease" as too much power is given to individual Ministers.

During the debate on the Foreign Interference (Countermeasures) Act 2021, he moved amendments he argued were needed to boost transparency and tackle the likelihood of elite capture resulting from the powers granted by the bill.

Other proposals were to nudge target groups through subsidies and leverage the large amount of data available to flag health issues out to patients at visits to the doctor.

[22] On climate change and the environment, Perera raised an adjournment motion in 2016 calling on the Government to boost support for new industries with non-economic benefits, including renewable energy and environmental technology.
