Although Munro supported Pitt on the Regency question, there was speculation in Scottish Whig circles that his long-established control over Inverness Burghs, which rested on the wealth acquired during his erratic Indian military career, was under threat from Henry Dundas. In the event, neither the minister nor opposition made any move to unseat him in 1790 or 1796, when Fortrose and Inverness, where his power chiefly lay, were the returning burghs.
Shortly after the election of 1790 Lady Sutherland encountered Munro, ‘rather in the character of a fish out of water’, among the British upper set in Paris. He was absent from the division on the exemption of Scotland from the Test Act, 10 May 1791, reckoned ‘doubtful’. On 16 Dec. 1792, when soliciting local patronage, he told Dundas that although he had as yet received no summons of attendance for the new session he would ‘set off for the south soon’, but there is no record of his having voted or spoken in the House during this period.
