The executions last month of two convicted drug traffickers has reopened debate about the death penalty in Thailand.
They were the first executions in six years and marked the end of an unofficial moratorium.
At Bangkok's Bang Kwang prison, more than 700 prisoners are on death row.
Most Thai citizens favour executions, but the death penalty also makes many of the country's practising Buddhists uncomfortable, amid an attempt to reconcile capital punishment with Buddhist doctrines.
