Some countries require a candidate to secure more than 50 per cent of the votes cast to win the presidency.

If no one attains this threshold, then a second-round run-off election is carried out shortly after, with the two best performers facing off against each other.

This is a good system, as it continues to enshrine and protect what Mr Peh Chwee Hoe terms "the sanctity of one man, one vote" ("Electoral College system has its flaws"; June 30), while allowing the elected president to hold his head high, secure in the assurance that he has the support of the majority of voters ("Worthwhile to consider electoral college system" by Mr Ronnie Lee Kok Tong; June 29).
