To ask Her Majesty's Government how many electors with the same national insurance number appear on both the electoral register for the South Belfast constituency and that of Fermanagh and South Tyrone; and how many appear more than once in Northern Ireland constituency registers. [HL2116]

The Northern Ireland Office (NIO) does not hold copies of the electoral register for any constituency in Northern Ireland. The Chief Electoral Officer for Northern Ireland is responsible for maintaining the electoral register there and the noble Lord may wish to make inquiries relating to the register to the Chief Electoral Officer directly.
