 Since 2007, when local government elections in Scotland began to use the single transferable vote rather than the first-past-the-post system, the dominance of the Labour Party within the city started to decline.As a result of the 2017 United Kingdom local elections, the SNP was able to form a minority administration ending Labour's thirty-seven years of uninterrupted control.In the aftermath of the Russian Revolution of 1917 and the German Revolution of 1918–19, the city's frequent strikes and militant organisations caused serious alarm at Westminster, with one uprising in January 1919 prompting the Liberal Prime Minister, David Lloyd George, to deploy 10,000 soldiers and tanks on the city's streets.
