On the death of Sir Richard Myddelton, whose son had no desire to enter Parliament, his cousin, Robert Myddelton, stood for the county on the Chirk Castle interest at the ensuing by-election, but was defeated by Watkin Williams (Wynn). In 1722, having succeeded to the Chirk Castle estate, he stood again, with the support of the Administration, whom he requested to arrange for the shire election to precede that for the boroughs so that if he were defeated for the former he could be returned for the latter.1 Defeated for the county but returned for the boroughs, he voted with the Tories against the Government, even joining his opponent, Watkin Williams Wynn, in opposing a loyal address from the county on the Atterbury plot.2 He continued to oppose the Administration till his death, 5 Apr. 1733.
