Erle was returned at Wareham again in 1710 and 1713. In 1714, following the death of Queen Anne, Erle was appointed Lieutenant-General of the Ordnance for a second time. The same year, he was also made Governor of Portsmouth, replacing Lord North and Grey, whose loyalty to the new king was in doubt. Erle was returned as MP for Wareham at the 1715 general election. From 1715 until 1718 he was Father of the House. He was forced to resign all his posts and his seat in Parliament in March 1718 and received in return a pension of £1,200 a year.
