Mundy, a naval officer and son of the Tory Member for Derbyshire, stood again for Boroughbridge at the general election of 1820 on the interest of his brother-in-law, the 4th duke of Newcastle. He again faced a contest and campaigned actively in the constituency. There was a double return in favour of Newcastle’s opponents, but Mundy was seated on petition.
It is possible that he was the Mundy who seconded Robert Bransby Cooper’s successful resolution to prevent Members from voting on private bills in committees which they had not attended, 20 Feb. 1827. In the Berwick election committee, 24 Mar., he reportedly voted to find John Gladstone* guilty of treating.
