It is a constant fight to keep the house clean. As long as the core leadership is clean, any back sliding can be brought under control and the house cleaned up. What the PAP government cannot ensure is that if it loses an election, a non-PAP government will remain honest. Therefore we have installed constitutional safeguards to meet such an eventuality. We amended the constitution to have the president popularly elected not by parliament but by the whole electorate and [he] has a veto power on the spending of the country’s reserves by the cabinet. The president now also has the power to overrule any prime minister who stops or holds up an investigation for corruption against any of his ministers or senior officials or himself.
