Since the 2011 polls, Lee’s party has lost two by-elections. The government “paid a political price” with the infrastructure strains as a result of a bigger population, the prime minister said last month.
In other developments, Lee’s father, Lee Kuan Yew (李光耀), Singapore’s first prime minister, has been discharged from hospital after suffering from a condition linked to a prolonged irregular heartbeat.
The elder Lee, 89, was sent to the Singapore General Hospital after the suspected transient ischemic attack, according to a statement from the prime minister’s office.
The office said Lee Kuan Yew is resting at home.
