 A few weeks after the election, the leader of the Unitary Socialist Party Giacomo Matteotti requested, during his speech in front of the Parliament that the elections be annulled because of the irregularities.On June 10, Matteotti was assassinated by Fascist Blackshirts and his murder provoked a momentary crisis in the Mussolini government.Mussolini ordered a cover-up, but witnesses saw the car that transported Matteotti's body parked outside Matteotti's residence, which linked Amerigo Dumini (a Fascist prominent in Mussolini's personal escort) to the murder.
