DAP central executive committee member Ronnie Liu has warned Pakatan Harapan against becoming more Malay-centric following its defeat in the Semenyih by-election.He said there will be some Harapan leaders who will get spooked by Semenyih and have a knee-jerk reaction, calling for it to start becoming more Malay-centric."In other words, they want Harapan to try to 'out-Umno' Umno and perhaps even to 'out-PAS' PAS and if Harapan or even its component parties go down this route, it will be a colossal mistake of the highest order.
