He was supported by the Duke of Glocester, the Bishop of Durham (Dr.Barrington), the Earls Moira, Selkirk, and Roslyn, and the Lords Holland, King, and Hood.

The opponents of the bill were the Duke of Clarence, the Earls Westmoreland and St.Vincent, and the Lords Sidmouth, Eldon, and Hawkesbury.

The sentiments too, which he delivered on this occasion, ought not to be forgotten.
