Winston Churchill: Churchill began his career as a Conservative MP in 1900. Disagreeing with his party's stance on trade tariffs, he defected to the Liberal Party in 1904. Two decades later, in 1924, due to his growing opposition to the rise of the Labour Party, he rejoined the Conservative Party, giving rise to his famous quip: "Anyone can rat, but it takes a certain ingenuity to re-rat."
William Gladstone: Considered one of the dominant figures of the Victorian era, Gladstone began his career in 1832 as a "High Tory" (Conservative). Over the decades, his views shifted toward free trade and social reform. He eventually joined the newly formed Liberal Party in 1859, going on to serve as a Liberal Prime Minister four separate times.
Ramsay MacDonald: As the first-ever Labour Prime Minister, MacDonald faced a severe economic crisis in 1931. When his Cabinet split over budget cuts, he chose to break away from the mainstream Labour Party. He formed the National Labour Organisation and headed a "National Government" coalition that was overwhelmingly backed by Conservatives. This led to him being expelled from the main Labour Party and labelled a traitor by former colleagues." |
