A proposed ballot question on allowing Newport Grand to offer casino games is on its way to Rhode Island Gov. Lincoln Chafee for his signature.

Chafee’s authorization, which is likely to happen next week, would formally send the referendum to the fall ballot.

Newport Grand wants to offer table games such as poker and blackjack to compete with casinos that could be built in southeastern Massachusetts.

The state’s General Assembly voted to approve the referendum for the ballot this week.

The state Constitution requires casino proposals to be approved by voters statewide and in the host community.

Lawmakers have already scheduled a referendum this fall on authorizing table games at the Twin River slot parlor in Lincoln.
