DUP MP Ian Paisley's Westminster bill which seeks to require a "super-majority" in future UK referendums is set to be debated on St Patrick's Day.
The Referendums (Supermajority) Bill has been listed for its second reading in the House of Commons on March 17.
It will be the first opportunity for MPs to debate the main principles of the bill, which aims to require a "super-majority" to permit UK constitutional change in future referendums.
