Less than three weeks after a landslide general election win by the ruling party, Singapore has announced a new Cabinet structure in a pitch for leadership renewal, with some senior officeholders taking on wider coordinating roles overseeing younger ministers.

Prime Minister Lee Hsien Loong, who has helmed the city-state's parliament since 2004, described the change as "bold," saying Monday that countries including Britain and Indonesia had made similar moves.

In the new Cabinet structure, senior officeholders of three portfolios — home affairs, finance and national development — will drop their previous duties and take on guiding roles. Of the three, two will continue to hold the roles of deputy prime minister, while the other will take on a new transport portfolio.
