In 1990, Goh Chok Tong succeeded Lee and became Singapore's second prime minister. During Goh's tenure, the country went through the 1997 Asian financial crisis and the 2003 SARS outbreak. In 2004, Lee Hsien Loong, the eldest son of Lee Kuan Yew, became the country's third prime minister. Lee Hsien Loong's tenure included the 2008 global financial crisis, the resolution of a dispute over land ownership at Tanjong Pagar railway station between Singapore and Malaysia, and the introduction of the 2 integrated resorts (IRs), located at the Marina Bay Sands and Resorts World Sentosa. The People's Action Party (PAP) suffered its worst ever electoral results in 2011, winning just 60% of votes, amidst debate over issues including the influx of foreign workers and the high cost of living. On 23 March 2015, Lee Kuan Yew died, and a one-week period of public mourning was observed nationwide. Subsequently, the PAP regained its dominance in Parliament through the September general election, receiving 69.9% of the popular vote, although this remained lower than the 2001 tally of 75.3% and the 1968 tally of 86.7%. The 2020 election saw the PAP drop to 61% of the vote, while the opposition Workers' Party took 10 of the 93 seats, the highest number ever won by an opposition party.
