The Derby Dilly was a name given to a group of dissident Whigs who split from the main party under the leadership of Edward, Lord Stanley on the issue of the reorganisation of the Church of Ireland in 1834. Stanley and three others resigned from the cabinet of Lord Grey on this particular issue but other factors included their fear that the Whigs were appeasing their radical and Irish allies with further reforms. The group's name 'Derby Dilly' is a reference to Stanley being the heir of the Earl of Derby. Formation In 1830 Lord Grey had formed a government that had achieved political success by passing the Reform Act 1832 and abolishing slavery in the British Empire.

They were at first known unofficially as the 'Stanleyites', as they seemed more of an old-style parliamentary faction that was familiar in British politics from the 18th and early 19th centuries. However, the group soon received a new name from its political opponents to which they are now best remembered: 'The Derby Dilly'. It was an allusion to a type of stagecoach called the 'Derby Dilly' (short for 'Diligence') and referred to Stanley's hereditary family title 'Earl of Derby'. Remembering Stanley's remark that when he had left the cabinet that it had led to an 'upsetting of the ministerial coach', the Irish nationalist leader Daniel O'Connell labelled the group the 'Derby Dilly', with a clever reference to the lines of a poem by George Canning and others, 'The Loves of the Triangles'.
