Asked whether the loss was due to PH’s failure to honour its manifesto pledges, and the steps needed to be taken going forward, Dr Mahathir said there will be action taken by both the government via Cabinet Ministers as well as the respective component parties.
“We’ve been told where it had gone wrong. It is as if there are factions, but there do not seem to be factions among the leadership, maybe with some at the grassroots level who are not happy and do not know the real facts and so they give out strong views,” he said.
Asked if PH’s delay in appointing Parliamentary-level coordinators was among the reasons for the by-election defeat, Dr Mahathir said: “There are many reasons for the results of the by-election. We have to think of all the different reasons, not just because of the issue of coordinators.
"Many other issues (are) taken into consideration by the people, and maybe they want to remind us and (so) we are reminded."
Meanwhile, Dr Mahathir said PH was a coalition party that practised freedom of speech, and if there were problems, they could be raised at their respective committee levels or the presidential council meeting to ensure confidentiality.
