The Singapore Democratic Party (SDP) conducted its first walkabout in Punggol East on Sunday.

Led by secretary-general Chee Soon Juan, a group of 50 members and volunteers visited Rivervale Mall and 20 housing blocks this morning.

Also part of the group were party treasurer Vincent Wijeysingha, and Dr Paul Tambyah, raising speculation that either may be chosen as SDP's candidate in the single-member constituency. Dr Wijeysingha is a lecturer and Dr Tambyah is an infectious disease expert who has spoken at SDP's rallies and worked on several of its policy papers.
