Gabriel Lim, former personal private secretary to the prime minister, will take up the post from Dec 8.
The announcements were made by Singapore’s Ministry of Communications and Information.
Koh had been in the post two years. She is credited by the ministry with “focussing [the MDA] on strengthening consumer protection, including safeguards for pay-TV consumers, parental controls of the internet, and launch of the ‘Safer Internet Day’ in Singapore, and [overseeing] the launch of the nation-wide digital TV initiative and spearheaded the Digital TV Assistance Scheme to help needy households manage the switchover to digital TV.”
Koh will be given “another leadership posting in 2015,” the ministry said.
