Prime Minister Lee Hsien Loong on Wednesday announced several changes to the Cabinet and other political appointments. On the announcement, SMU Associate Professor of Law Eugene Tan said: “The changes announced, indicated the conscious effort to introduce and test new office holders." He added: "The process to put in place a 4G leadership takes on greater salience and urgency now that we are almost mid-way through the life of the current Parliament. There is a sense that the new blood needs to be more visible and to learn the ropes."
