To an extent, SDP's giving NSP Sembawang allowed NSP to field candidates which it had meant for Marine Parade. Otherwise, more people will resign from NSP.
However, I am someone who feels NSP should return Sembawang to SDP.
Nsp under the current leadership didnt just lost territory to WP, they lost Mountbatten to SPP, jurong GRC to SFP , CCK to PPP without getting anything from them other than the assurance of no 3cf. This reflect very badly of the party leadership.
