DUP MP Ian Paisley has denied his Westminster bid to require a "super-majority" in future UK referendums is "changing the goalposts" for a border poll on a united Ireland.
Mr Paisley argued his bill echoes the sentiments of nationalist leaders who have said a majority significantly above "50% plus one" would be preferable in an Irish unity vote to ensure "stability".
The Brexit-backing MP said he had "reflected" upon the narrow majority of the 2016 EU referendum and "experienced the acrimony that has since flown from then".
