In December 1851 Lord John Russell, the Prime Minister, required Lord Palmerston to resign his office of Foreign Secretary, on the ground that he had exceeded his authority as Secretary of State in his communications on his own authority to France with reference to the recognition of the _coup d’état_ of Louis Napoleon. Lord Palmerston had personally expressed his approval of the action to the French ambassador in London. The affair has passed into history and only concerns us here because Lady Palmerston fancied her husband was the victim of a conspiracy. She wrote angrily to this effect to Lord John, whom she had known since 1830, and who was one of her oldest friends. In his reply he told her that the tone of her letter would justify him in not answering it, but it was necessary for him to assure her that there had been no conspiracy, that he had acted alone to save others from responsibility. He further said that the loss of Lady Palmerston’s friendship added to the weight of his regret at the whole business. As a matter of fact, Lord Palmerston was soon asked to go back, and it is quite certain that it was Lady Palmerston who contrived to let it be known in the proper quarter that he was willing and anxious to do so. In 1868 Lady Palmerston asked Lord John, as Palmerston’s _oldest and best friend_--the italics are hers--to unveil the statue and window to Lord Palmerston’s memory in the town and abbey of Romsey. Lord John was only prevented from acceding to her request by the death of his brother-in-law, Lord Dunfermline. So that the difference between Lady Palmerston and Lord John was not very serious or lasting.
