Speaker Wade Mark is today expected to declare the seat of the constituency of St Joseph officially vacant.
The seat became vacant on Monday, 15 days after Mr. Mark invoked the Crossing of the Floor Act, removing former St Joseph MP Herbert Volney from the Parliament.
The former MP, who was elected to the seat in 2010 under the People’s Partnership, had 14 days to legally challenge or accept the declaration.
He resigned as MP last week and vowed to exit electoral politics for good.
Mr. Volney had resigned from the UNC in July.
After the seat is declared vacant, Prime Minister, Kamla Persad-Bissessar, will have 90 days to announce a by-election for the seat.
According to calculations, a by-election date may be announced no later than December 20.
