In 1628 he was returned to the third parliament of Charles for Ludgershall, Wiltshire, and was involved in drawing up and carrying the Petition of Right. In the session of 1629 he was one of the members responsible for the tumultuous passage in the House of Commons of the resolution against the illegal levy of tonnage and poundage, and, along with Sir John Eliot, Denzil Holles, Long, Valentine, William Strode, and the rest, he was sent back to the Tower. There he remained for eight months, deprived for a part of the time of the use of books and writing materials. He was then removed, under less rigorous conditions, to the Marshalsea, until Archbishop Laud arranged for him to be freed. Some years before, he had been appointed steward to the Earl of Kent, to whose seat, Wrest in Bedfordshire, he now retired.
