Answer
Member of Parliament, Charles Stewart Parnell, played a pivotal role in the House of Commons. He was a charismatic leader of the Irish Parliamentary Party, advocating for Irish Home Rule. Parnell's obstructionist tactics, such as filibustering and boycotting, disrupted parliamentary proceedings and drew attention to Irish grievances. His influence extended beyond Ireland, as he formed alliances with other political groups, including the Liberal Party, to advance his cause.
