[Update, Sept 14]: Halimah Yacob has been sworn in as Singapore's first woman president, on Thursday (Sept 14).
In her speech after being sworn in as Singapore's eighth President, Madam Halimah also said the presidency is a heavy responsibility and she will do her best. She said she has been energised and motivated by conviction and enthusiasm of Singaporeans she met over the last few weeks.
Prime Minister Lee Hsien Loong, in his speech at the Istana swearing-in ceremony, notes that Madam Halimah Yacob has overcome difficult challenges in her life. "Your story reflects the Singapore Story - how we have come this far together, and what we aspire to be as a nation."
Madam Halimah Yacob submitted her paperwork for the presidential election on Wednesday (Sept 13), making her officially Singapore's president-elect.
Madam Halimah Yacob was issued a Certificate of Eligibility by the Presidential Elections Committee on Monday (Sept 11).
The 63-year-old was the only presidential hopeful of three to receive the certificate, meaning the presidential election reserved for candidates from the Malay community is headed for a walkover.
The former unionist and Speaker of Parliament is set to be Singapore's first female president.
On Wednesday, she will turn up at the People's Association headquarters in King George's Avenue to file her nomination papers. If they are in order, the returning officer will declare her president-elect, and she will start her term on Thursday.
