Chamberlain returned to office in H. H. Asquith's wartime coalition government in May 1915, as Secretary of State for India, but resigned to take responsibility for the disastrous Kut Campaign. He again returned to office in David Lloyd George's coalition government, once again serving as Chancellor of the Exchequer. He then served as Conservative Party leader in the Commons (1921–2), before resigning after the Carlton Club meeting voted to end the Lloyd George Coalition.
