Passage: Both the election of January 1910, and that of December 1910 produced a hung parliament with an almost identical number of seats won by the governing Liberal Party and the Conservative Party. This was due both to the constitutional crisis and to the rise of the Labour Party. The elections of 1929 resulted in the last hung parliament for many years; in the meantime, Labour had replaced the Liberals as one of the two dominating parties.

Question: when were the elections held?
January 1910, and that of December 1910
