Gladstone returned to power after the 1892 general election; he was 82 years old. Victoria objected when Gladstone proposed appointing the Radical MP Henry Labouchere to the Cabinet, so Gladstone agreed not to appoint him. In 1894, Gladstone retired and, without consulting the outgoing prime minister, Victoria appointed Lord Rosebery as prime minister. His government was weak, and the following year Lord Salisbury replaced him. Salisbury remained prime minister for the remainder of Victoria's reign.
