Sutin Klungsang (Thai: สุทิน คลังแสง; born 9 March 1961), is a Thai politician, educator and current Thai Minister of Defence.[1]
Sutin graduated with a Bachelor's degree in Education from Srinakharinwirot University, Maha Sarakham campus, and a Master's degree in Thai Studies Branch from Mahasarakham University and a Doctor of Philosophy from Magadh University, India.[2]
After the 2019 Thai general election, he shone heavily in politics, being a key figure of the Pheu Thai Party in the heated parliamentary debate on Prime Minister Prayut Chan-o-cha and he was appointed as Chairman of the Opposition whips in the 2019 election, looking for a point to attack the government of Prayut.
On 1 September 2023, he was appointed Minister of Defence, becoming the first civilian in Thailand to hold this position without holding the position of Prime Minister.[3]
