WP needs to take leaf out of Chiam's parliamentary speeches. Never write and deliver speeches that resemble a response to a policy white paper or a proposal for a new policy. Identify a few key issues and work the room. Parliament is not where you write out solutions or alternatives. Parliament is where you make your position crystal clear, ask the govt to account for their actions.
These things can be worked out by formal coaching. Sylvia, Pritam, JJ and LTK should give them lessons on it.
