TheJanuary 1910 United Kingdom general election was held from 15 January to 10 February 1910 to elect all 670 members of theHouse of Commons. Called amid aconstitutional crisis after theConservative-dominatedHouse of Lords rejected thePeople's Budget, theLiberal government, seeking a mandate, lost their majority.
The result was ahung parliament:Arthur Balfour’sConservatives and theirLiberal Unionist allies won the most votes, butAsquith’sLiberals secured the most seats, edging out the Conservatives by two. WithIrish Parliamentary Party support, Asquith remained in power. Another election followed inDecember.
TheLabour Party, led byArthur 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, ofLib Lab MPs from the Liberal Party to Labour.

Liberals had to rely on theIrish Parliamentary Party andLabour for their parliamentary majority. As the price for their continued support, the Irish nationalists demanded measures to remove the Lords' veto so that they could no longer blockIrish Home Rule. The Lords accepted the electoral mandate and approved the People's Budget on 28 April 1910,[4] but contention between the government and the Lords continued throughout the year. The government called afurther election in December 1910 to get a mandate for theParliament Act 1911, which would prevent the House of Lords from permanently blocking legislation.
