Lon Nol
Five days later, Oum Mannorine, the half-brother of Sihanouk's wife Monique, was summoned to the National Assembly to answer corruption charges. On that night after the hearing, Mannorine ordered troops under his command to arrest Lon Nol and Sirik Matak, but ended up getting arrested by Lon Nol's troops instead. On 18 March 1970 the National Assembly voted to depose Sihanouk, allowing Lon Nol to assume emergency powers.
