Female President for Singapore?

From the Diplomat:

The recent victory of Yingluck Shinawatra, who will become Thailand’s first female prime minister, has inspired some Singaporeans to ask whether it’s also time for the prosperous city state to elect its first female president. Singapore is set to choose its new president, a largely ceremonial position, next month.

But electing a female president isn’t that easy as choosing a female member of parliament. After reviewing the minimum qualifications that a candidate must pass, it seems there will be some difficulty in finding eligible female nominees.

According to Grace Ke of the Association of Women for Action and Research, Singapore has had only one female minister in its history, and has never had a female chief justice, speaker, attorney general, Public Service Commission chairman or auditor general.
