Can a morally scrupulous English gentleman make an effective Prime Minister? This is one of the enduringly fascinating problems posed in The Prime Minister (1876). And as Plantaganet Palliser, Duke of Omnium, overenthusiastically supported by Lady Glencora, presides over the Coalition government, Trollope reaches into the highest echelons of the English establishment, depicting political realities rather than ideology, portraying social, sexual and domestic politics as well as the public variety. The world of the novel is perplexed and dominated by the handsome impostor Ferdinand Lopez. Even the Duke and Duchess are not immune to his malign influence, as Lopez pursues Emily Wharton for her charm and her fortune, and plots to win membership of that most exclusive of English clubs, the Houses of Parliament.
Plantaganet Palliser, Prime Minister of England - a man of power and prestige, with all the breeding and inherited wealth that goes with it - is appalled at the inexorable rise of Ferdinand Lopez. An exotic impostor, seemingly from nowhere, Lopez has society at his feet, while well-connected ladies vie with each other to exert influence on his behalf - even Palliser's own wife, Lady Glencora. But when the interloper makes a socially advantageous marriage, Palliser must decide whether to stand by his wife's support for Lopez in a by-election or leave him to face exposure as a fortune-hunting adventurer. A novel of social, sexual and domestic politics, The Prime Minister raises one of the most enduring questions in government - whether a morally scrupulous gentleman can make an effective leader.
