H. H. Asquith Liberal
The January 1910 UK general election was held from 15 January to 10 February 1910. Called amid a constitutional crisis after the Conservative-dominated House of Lords rejected the People's Budget, the Liberal government, seeking a mandate, lost their majority.
The result was a hung parliament: Arthur Balfour’s Conservatives and their Liberal Unionist allies won the most votes, but Asquith’s Liberals secured the most seats, edging out the Conservatives by two. With Irish Parliamentary Party support, Asquith remained in power. Another election followed in December.
The Labour Party, led by Arthur Henderson, returned 40 MPs. Much of this apparent increase (from the 29 Labour MPs elected in 1906) came from the defection, a few years earlier, of Lib Lab MPs from the Liberal Party to Labour.
