The Fifth Earl of Rosebery was the most glamorous Liberal politician of the late Victorian age. Charismatic, enlightened, wealthy and intellectually brilliant, he once said that he had three ambitions: to marry an heiress, win the Derby and become Prime Minister. By his mid-forties, he had achieved all three. But his political career was clouded by his mercurial character. Self-centred, impulsive and neurotic, he shrouded himself in mystery and was caught up in many of the greatest scandals of his era. Now, using a wealth of archival material, award-winning author Leo McKinstry reveals the dramatic, compelling story behind this paradoxical figure.
