 In 1916, at the height of World War I, Lloyd George's government had taken control of the industry, but with inflation the purchasing power of miners' wages had fallen.After the war government control was relaxed, and the triple alliance was revived.In 1919, as a conciliatory measure, the government appointed a royal commission to investigate the industry under Mr Justice Sankey, which recommended the nationalisation of mining royalties but did not explain how this would be achieved.
