Lord Powis wrote to George Grenville, 28 Aug. 1764,
Wallop was returned for Whitchurch on his brother’s interest. There is no record of any vote or speech by him in the House; in Robinson’s two surveys on the royal marriage bill, March 1772, he was listed as ‘pro, absent’; and again as ‘pro’ in the electoral survey of September 1774. He did not stand again for Parliament; and died in August 1794.
