While he served the Duke of Newcastle, he began to flatter others with nice words, which gave him the job of Receiver of Land Tax for Suffolk, but did not do much else until King George III was made king in 1760, when he left Newcastle for the new king. In 1767 he was made king's advocate, mostly because there was no one else to do it. In 1767 he served as Vice-Chancellor of the University of Cambridge for a year and in 1768.
