On 22 May, Thailand’s military declared martial law. On 24 May, they took power in a coup.
They have suspended the constitution, banned demonstrations and detained politicians including Yingluck Shinawatra who, until very recently, was prime minister. The head of the military, General Prayuth Chan-ocha, has appointed himself the new prime minister.
The coup follows a court ruling early this month removing Shinawatra from her position as prime minister on the grounds that she had acted illegally by moving her national security chief to another position.
