The constituency has a
Unionist plurality although, in many elections,
nationalists have polled 40% of the vote, and the middle-of-the-road
Alliance Party sometimes above 10%. Until the 2010 election the main interest in elections had been the contest between the
Ulster Unionist Party and the
Democratic Unionist Party. The UUP were normally ahead of the DUP until the 2001 general election, when the DUP finally overtook them. The 2001 election was seen at a province-wide level as a battle over the
Belfast Agreement, with the DUP opposed to it and most of the UUP in favour. However, that situation was seemingly reversed in East Londonderry, in which the sitting Ulster Unionist MP, William Ross, was completely opposed to all involvement with the Agreement and its institutions, whilst the DUP candidate, Gregory Campbell, was a minister in the executive set up by the agreement. Many commentators joked that the DUP's gain meant that East Londonderry now had a
more pro-agreement MP than before. In the
2016 EU referendum 21,098 people in the constituency voted to remain in the European Union, 19,455 voted to leave, and 10 votes were rejected. Unionist candidates failed to get a majority of the votes for the first time at the 2019 election, although they secured a plurality of votes. The seat had a considerable swing to Sinn Féin in the 2024 general election of over 12%, but the DUP retained the constituency, albeit with a very narrow majority of 179 votes. == Members of Parliament ==
