Pakatan Harapan's youngest minister Syed Saddiq Syed Abdul Rahman is determined to prove his critics wrong.

In an interview with Malaysiakini shortly after he arrived at the Subang Jaya airport from Johor Bahru yesterday, the 25-year-old said similar doubts were also raised in the past over his appointments as Bersatu Youth chief, the sole youth representative in Harapan's presidential council, as well as the coalition's candidate for the Muar parliamentary seat against former Umno deputy minister Razali Ibrahim.
