2nd Marquess of Buckingham. The former Portland Whigs who remained active in politics had by now largely returned to their former Whig allegiances. In 1822, Prime Minister Lord Liverpool bought the group's support for the government by creating Buckingham as Duke of Buckingham and Chandos and bringing in several of his supporters, notably Charles Williams-Wynn, who became President of the Board of Control, into the government. In the years that followed, the Grenvillites disappeared as a distinct political faction.
