I don't think there needs to have WP in the picture of SPP. For now, the pie is just nice for everybody.
WP needs to step into Tampines and Tanjong Pagar. The former is between the WP top two wards of EC and Aljunied and chopped by a village party 5 times they cannot win. TP is walkover, so cannot complain.
It's also penalty for the opposition personality most critical and opposed to WP, that the chap cannot ever return to that ward without sparing $16000.
