Candidates.
On 2 May, the candidates for the by-election were selected. The Altrincham Unionist Association chose George Hamilton of Knutsford, while the Liberals nominated Lawrence Kay-Shuttleworth, eldest son of Lord Shuttleworth, Lord-Lieutenant of Lancashire.
Campaign.
The writ for the by-election was moved on 8 May, and the date for the election was set as 28 May. The delay was due to allow for the week-long Whitsun holiday enjoyed by Manchester workers.
The Liberals had formed a minority government with the support of Irish Nationalists. As the price of Nationalist support the government was attempting to introduce Home Rule for Ireland.
One of the main issues in the contest was Home Rule The Irish Nationalist leaders John Redmond and T P O'Connor urged Irish voters to support Kay-Shuttleworth. Hamilton spoke out in support of the Ulster Unionists who were threatening armed insurrection to resist devolution. This led to the Manchester Guardian launching an attack on the Conservative candidate as a "revolutionist". The apparent lack of support for Hamilton by Kebty-Fletcher, and his treatment by the local Unionist Party caused some controversy, although he eventually issued a letter discounting the story.
The government majority had been reduced from 126 to 106 following the loss of a string of by-elections since December 1910. The Liberals hoped to reverse this trend by regaining the Altrincham seat.
The Liberal Government was planning on passing a Plural Voting Bill that sought to prevent electors who appeared on the electoral register twice from voting twice. Liberal and Unionist HQs were in agreement over 25 seats that were won by Unionists in December 1910 because of plural voting, and this was one of those constituencies.
The Altrincham Trades Council called on workers to vote against Hamilton, who as a major employer refused to pay union rates.
Result.
The Unionists easily held the seat with a greatly increased majority. This was however partly explained by an increase in the electorate of 1,939 voters since 1910. Nevertheless, the result was deeply disappointing for the government. In contrast, Unionists were delighted, and Lord Londonderry, President of the Ulster Unionist Council sent a message of congratulation to Hamilton.
