When the Whigs finally came to power in 1830, Ebrington played a significant part in the passing of the Great Reform Act. After the Commons passed the second bill, Ebrington convened a meeting of 100 reformist Whigs, urging strong measures should the Lords reject it, and acting as leader of a pressure group lobbying the Whig leadership: Ebrington himself appeared on a list of potential peer-creations that was drawn up to increase the pressure on the Lords. When the Government resigned in the face of Tory intransigence in the House of Lords, Ebrington took the lead, despite leadership hesitations, in moving that the House of Commons implore the King “to call to his councils such persons only as will carry into effect unimpaired in all its essential provisions that Bill for reforming the Representation of the people which has recently passed this House”.
