I want to know the answer to the following question:
Who returned as prime minister when Disraeli lost the general election in 1880?
All the background I'm provided with is that "Between April 1877 and February 1878, she threatened five times to abdicate while pressuring Disraeli to act against Russia during the Russo-Turkish War, but her threats had no impact on the events or their conclusion with the Congress of Berlin.". Is that enough to answer the question?
