Legislative size (voting members)
Trinidad and Tobago
Official webpage of the Elections and Boundaries Commission
'For the purposes of Parliamentary elections, the country is divided into 41 electoral districts or constituencies: thirty nine (39) in Trinidad and two (2) in Tobago.'
It is technically possible for there to be 42 voting members if the Speaker elected is not a member of the House (there is no provision stating that such a Speaker does not have a casting vote).
