In 2010, Sinn Féin opted not to stand against the SDLP to avoid splitting the nationalist vote. This effort was successful as the SDLP won the seat with a majority of 6,000. This was the seat in which the Alliance Party had their second-best showing, polling 15% of the votes. Alasdair McDonnell retained the seat in May 2015, with only 24.5% of the vote, as Sinn Féin opted to stand. This is the smallest proportion of the vote a winning candidate has ever achieved in a UK general election.
