Passage: During Newton's trial, a motion in Parliament sought to investigate Parke's allegations of a cover-up. Henry Labouchère, a Member of Parliament from the Radical wing of the Liberal Party, was staunchly against homosexuality and had campaigned successfully to add the "gross indecency" amendment (known as the "Labouchère Amendment") to the Criminal Law Amendment Act 1885. He was convinced that the conspiracy to cover up the scandal went further up the government than assumed. Labouchère made his suspicions known in Parliament on 28 February 1890. He denied that "a gentleman of very high position"—presumably Prince Albert Victor—was in any way involved with the scandal, but accused the government of conspiracy to pervert the course of justice. He suggested that the Prime Minister Lord Salisbury and other officials colluded to hamper the investigation, allowing Somerset and Hammond to escape, delaying the trials and failing to prosecute the case with vigour. Labouchère's accusations were rebutted by the Attorney General, Sir Richard Webster, who was also the prosecutor in the Newton case. Charles Russell, who had prosecuted Parke and was defending Newton, sat on the Liberal benches with Labouchère but refused to be drawn into the debate. After an often passionate debate over seven hours, during which Labouchère was expelled from Parliament after saying "I do not believe Lord Salisbury" and refusing to withdraw his remark, the motion was defeated by a wide margin, 206–66. In a subsequent speech to the House of Lords, Salisbury bore witness against himself by suggesting his memory of his handling of the affair was defective.

Question: How long was Labouchere's Parliament debate before he was thrown out?
over seven hours
