The Ninth Duke of Manchester succeeded his father in the dukedom in 1892 at the age of fifteen and later took his seat on the Liberal benches in the House of Lords. When the Liberals came to power in December 1905 under Sir Henry Campbell-Bannerman, he was appointed Captain of the Yeomen of the Guard. He retained this post until April 1907, but never held ministerial office again. Apart from his political career he also achieved the rank of Captain in the Lancashire Fusiliers.
The ninth duke went bankrupt as they say as we have heard because his trustees were stealing his funds. All public information if you do research.
