SINGAPORE - The ruling People's Action Party (PAP) marked its anniversary on Saturday (Nov 21) with posts online in which the party pledged to do its best and continue working with Singaporeans to meet challenges that lie ahead.

Prime Minister Lee Hsien Loong, in a Facebook post, remembered how his late father Lee Kuan Yew and other PAP pioneer leaders had joined him in a celebration of the party's 60th anniversary at Victoria Memorial Hall last year.

"A lot has happened since then. The People's Action Party has won a renewed mandate from the people. We must hold on to the passion and values that have brought us here, and continue to serve Singaporeans wholeheartedly, competently and responsibly," PM Lee wrote.

"Our goal remains to build a fair and just society based on multi-racialism, honesty, meritocracy and self-reliance."

Addressing Singaporeans in an e-mail, Deputy Prime Minister Teo Chee Hean thanked them for placing their trust in the PAP.

Mr Teo highlighted how Singapore's people was its only resource in the early years, but that their unity had given the country impetus to grow from strength to strength.

"The PAP strived hard to live up to the desire of Singaporeans for an honest, efficient, reliable and responsible government," he said.
