Northern Ireland will lose two MPs in the next general election as part of a reform of representation at Westminster.
Constituency lines will be redrawn for the 2015 poll, the Boundary Commission for Northern Ireland said.
It is part of a UK-wide reduction in the number of MPs from 650 to 600. Northern Ireland will have 16 seats instead of 18.
The commission will put its final recommendations to the Northern Ireland Secretary by October 2013.
