On 24 February 2010, the alliance announced 9 of the 18 candidates who were to run in the
2010 United Kingdom general election. The UUP's sole Member of Parliament (MP) from the 2005 general election,
Sylvia, Lady Hermon for
North Down, had expressed public dissatisfaction with the arrangement since early 2009, and left the UUP in March 2010, deciding to contest the
forthcoming general election as an
Independent. As such, the alliance had no incumbent MPs. On 7 April 2010 the candidate for
Fermanagh and South Tyrone,
Tom Elliott, withdrew in favour of
Independent Rodney Connor, leaving that constituency without a Unionist Party candidate. The Conservative and UUP alliance failed to gain any seats in the election. The UUP lost their only seat in North Down to Hermon's independent campaign, and Connor also lost Fermanagh and South Tyrone. Across Northern Ireland, the joint share of the vote was 15.2%. ==End of the alliance==
