During the summer of 1875, Chaplin remained in London rather than attend Brighton races, in order to assist Disraeli in supporting the Merchant Shipping Bill against the opposition of Samuel Plimsoll. Disraeli wrote to Lady Bradford on 30 July: "He has never left my side, and his aid has been invaluable. He is a natural orator and a debater too. He is the best speaker in the House of Commons or will be. Mark my words". Chaplin also supported Disraeli's government against Liberal opposition during the debates on the Royal Titles Bill, which conferred on Queen Victoria the title "Empress of India".
