This coalition government lasted until 1916, when the Unionists became dissatisfied with Asquith and the Liberals' conduct of affairs, particularly over the Battle of the Somme.[17] What would prove to be the last majority-Liberal government collapsed[18] as a result of the political manoeuvrings of Andrew Bonar Law (leader of the Conservatives), Sir Edward Carson (leader of the Ulster Unionists), and David Lloyd George (then a minister in the cabinet). Law, who had few allies outside his own party, lacked sufficient support to form a new coalition; the Liberal Lloyd George, on the other hand, enjoyed much wider support and duly formed a majority-Conservative coalition government.[16] Asquith was still the party head but he and his followers moved to the opposition benches in Parliament.[18]
