For a country whose press freedom ranks alongside the likes of Libya, Belarus and Iraq, Singapore is enjoying a surprisingly vibrant media debate ahead of the city-state’s general election tomorrow — aided by the growing reach of social media.

Nine out of 10 Singaporeans own a smartphone — the highest penetration rate in the world, according to a Deloitte report — creating the platform for a political forum. The online conversation stands in contrast to Singapore’s mainstream media, which according to US campaign group Freedom House “remain tightly constrained. All domestic newspapers, radio stations, and television channels are owned by companies linked to the government.”

Singapore ranks 153rd out of 180 countries in the 2015 World Press Freedom Index. There are curbs on online content and private ownership of satellite dishes is banned.
