Guise came from an old Gloucestershire family and held estates in the county that reputedly yielded £7,000 a year. He had entered politics as a reformer, but tempered his radicalism in order to secure a seat for Gloucestershire in 1811, and thus broke the domination of the Whig earls of Berkeley and the Tory dukes of Beaufort by championing the cause of the county freeholders.
Although absent from the early divisions of the session, Guise had a reputation as ‘the poor man’s friend’, and was said to have ‘abhorred oppression’.
Guise continued to support reform in the 1834 session, voting for the repeal of malt duty, 27 Feb. 1834, and supporting Lord Althorp’s motion that church rates be replaced by a central grant raised from land tax, 21 Apr. He divided in favour of Edward Strutt’s amendment for a select committee to inquire into the pensions list, 5 May 1834, when he also presented petitions for the better observance of the Sabbath.
His death having been prematurely announced by The Times, 19 July 1834, Guise died four days later after a ‘severe and alarming illness’ at Rendcomb Park, near Cirencester, where he had generally resided when in Gloucestershire. He was succeeded by his brother, Major General Sir John Wright Guise (1777-1865).
