He served as Groom of the Bedchamber to the Duke of York from 1665 to 1672 and to King Charles II from 1673 to 1678. During this time, he was also made envoy-extraordinary to France between 1672 and 1673 and between 1678 and 1682.[2]
In 1673, he was elected Member of Parliament in an irregular election for Newark, which was eventually declared void in 1677.[3] In the subsequent by-election Savile was properly re-elected, sitting until 1679. He was elected again in 1685, sitting until 1687.
In 1671, a Thomas Muddyman reported to Rochester that Savile had broken into the bedroom of "Lady Northumberland" (presumably Elizabeth Percy, Countess of Northumberland whose husband Josceline Percy, 11th Earl of Northumberland had died in 1670) with the intention of raping her.[8] In 1675, members of the gang, including Buckhurst, Savile, Rochester, and Sheppard, destroyed a valuable pyramidical glass sundial in the Privy Garden of the Palace of Whitehall.[9] Rochester was heard to exclaim "what does thou stand here to fuck time!" before destroying the piece with Sheppard.[10][9]
