By the beginning of James I’s reign, Fleetwood was well established as receiver-general of the Court of Wards. Knighted at the Coronation, he was returned to the first Jacobean Parliament for Middlesex, having last represented the county in 1589. His renewed interest in Parliament may have stemmed from the fact that the master of the Wards, Lord Cecil (Robert Cecil†), intended, through his spokesman Sir Robert Wroth I, to offer the Commons the abolition of wardship in return for a fixed annual composition. However, Fleetwood’s income was probably not threatened by Cecil’s proposed reform and so it is not altogether surprising that, unlike two other officers of the court of Wards who had seats in the Commons, John Hare and Sir Edward Lewknor I, he was not named to the committee appointed to consider Wroth’s motion when it was laid before the House on 23 Mar. 1604.
Fleetwood is difficult to distinguish in the parliamentary records from his namesake and second cousin, Sir William Fleetwood II, the Member for Buckinghamshire, although between 1604 and 1607 he was certainly named to at least four legislative committees. As receiver-general of the Court of Wards, he was appointed to consider a measure to allow the guardians of the Bedfordshire lunatic Robert Tompson to create a jointure in the event that Tompson’s son and heir married (24 Feb. 1607). He was also placed on committees for bills to prohibit married men from living in college with their families (14 June 1604), to naturalize Sir David Foulis (18 Apr. 1606) and to repeal a clause in the 1604 Watermen’s Act (13 Mar. 1607).
Fleetwood was in financial difficulty by November 1604, when he sold his lease of Cranford St. John manor to Sir Roger Aston* for £1,500.
