Ramotar says he is exercising his right to suspend the assembly for a maximum of six months. The procedure known as a "prorogue" is a step below dissolving parliament.
The president announced the measure yesterday and said it would allow his government to negotiate with the parliament on a legislative agenda without calling early elections.
But it also saves him from a no-confidence vote that he would likely have lost in an assembly controlled by the opposition that has blocked his initiatives in the South American country.
