Prime Minister Hun Sen has been named acted president of the Cambodian People’s Party, temporarily taking over duties for Chea Sim.
Chea Sim, 83, is a party stalwart and head of the Senate. He has fallen ill in recent months and has not appeared at key CPP events.
Chhim Phal Vorun, a spokesman for the party, said the position is temporary, and a permanent replacement is not being considered.
“We need not think about that yet,” he said.
A bodyguard for Chea Sim said he is recovering in a hospital in Vietnam and will return to Cambodia for the upcoming Chinese New Year.
