This left the nationalist parties unchanged with eight seats, the main unionist parties with eight seats (all DUP), the Alliance with one seat and an independent unionist with one seat. It is the first time since the partition of Ireland that unionist parties failed to secure a majority of Northern Ireland's Westminster seats in a general election, and also the first time Sinn Féin obtained the largest share of the vote in Northern Ireland at a general election. Notable results Secretary of State for Children, Schools and Families Ed Balls held his seat in Morley and Outwood by 1,101 votes, despite much anticipation of a "Portillo moment" (Despite this, he would indeed lose the seat at the following election). Minister of State for Borders and Immigration Phil Woolas retained Oldham East and Saddleworth by just 103 votes. However, following a legal challenge by his Liberal Democrat opponent, Elwyn Watkins, which found the local Labour campaign to have used negative and false information against Watkins, a new by-election was ordered and held on 13 January 2011. Woolas was barred from standing in this by-election whilst Watkins stood again, but Labour held the seat with an increased majority. Former Home Secretary Charles Clarke lost Norwich South by 310 votes to the Liberal Democrats. Another former Home Secretary, Jacqui Smith, lost Redditch on an above average 9.2% swing to the Conservatives. She had held the seat since 1997, and the seat was a key Conservative target. Her role in the 2009 expenses scandal contributed to her defeat. Minister of State for Health Mike O'Brien unexpectedly lost North Warwickshire, a seat he had held for 18 years, by just 54 votes to Conservative challenger Dan Byles. Green Party leader Caroline Lucas won Brighton Pavilion, becoming their first Westminster MP British National Party leader Nick Griffin finished in third place after a heavy loss in Barking to incumbent Labour MP Margaret Hodge In the wake of job losses at the local steel works, Solicitor General Vera Baird lost her seat of Redcar on a swing of 21.8% to Ian Swales of the Liberal Democrats. Glenda Jackson held Hampstead and Kilburn by just 42 votes (only 32% of the vote) ahead of the Conservatives, with the Liberal Democrats trailing less than 1,000 votes behind both other main parties. Incidentally, the seat has since become a safe Labour seat in the two elections held towards the end
