Poulett inherited his barony in 1649, his earlier attachment to the royalist cause alongside his father having subsequently become uncertain as he pursued his friendships and family connections with leading parliamentarians. It had been through the intercession of his wife’s brother-in-law, Sir Thomas Fairfax‡ (later 3rd Lord Fairfax [S]) that the Pouletts’ extensive west country estate was saved from a crippling compounding fine.
Poulett’s social and political prominence in post-Restoration Somerset rested on a considerable landholding in the county, the main focus of which was a concentration of manors in the area around Chard, and his country seat at Hinton St George.
During the elections to the House of Commons early in April 1660, he was pre-eminent in drawing together Cavalier backing to ensure the return of favourable county representatives, one of whom was his son-in-law Hugh Smith‡. At a by-election in March 1662 his eldest son and heir, John Poulett, later 3rd Baron Poulett, was returned unopposed as knight of the shire. This lead in setting the tenor of political support for the restored Stuarts locally also entailed, almost by default, the more long-term practical responsibilities of policing and the maintenance of order. The inadequate structures of command between central and local government became exacerbated after the death of the lord lieutenant, William Seymour, 2nd duke of Somerset, in October 1660, and the failure to appoint a successor until 1662.
In July 1661 Poulett was forced to petition the king for permission to proceed against one Whetham for unlawfully taking possession of the manor of Chard, which belonged to the bishopric of Bath and Wells, and it was almost certainly on this account that in February 1662 Poulett and his heir were appointed joint stewards of all the bishopric lands.
In the spring of 1660, Philip Wharton, 4th Baron Wharton, noted Poulett as one of the peers ‘with the king’. He first attended the Convention on 21 May 1660. His mansion at Chiswick, which his family had earlier acquired through marriage, provided him with a base within easy reach of Westminster. He attended on 58 days of the Convention, before the adjournment on 29 Aug. 1660, nearly 60 per cent of the total available days after he took his seat. On 13 June he was added to the committee on petitions, to which he was soon to present a case. On 19 July Philip Herbert, 5th earl of Pembroke, reported Poulett’s case from the committee of petitions, whereupon it was ordered that the cause be heard at the bar, by counsel on both sides, and that a proviso be considered when the indemnity and judicial proceedings bills were taken into consideration. On 2 Aug., after the case had been considered, a bill was ordered for restoring Poulett and his heirs to the lands conveyed by himself and his father, and their wives, to the trustees for the town of Lyme. The bill was given a first reading on 7 Aug. and committed on 13 Aug. to the committee dealing with similar legislation on behalf of William Cavendish, marquess of Newcastle. It never emerged from committee. On 23 Aug. the Lords referred a dispute between the freemen and inhabitants of Exeter and the mayor and aldermen of the same to five peers, one of whom was Poulett. Although the Convention resumed on 6 Nov. 1660, Poulett did not attend until the 12th. Thereafter he was present on 21 days of the remainder of the session, nearly 47 per cent of the total.
Poulett was in attendance when the new Parliament assembled on 8 May 1661, being named on the 11th to the committees for privileges and petitions. On 8 June he was given leave of absence to go into the country. On the 15th he registered his proxy with Robert Sutton, Baron Lexinton, and he was last recorded as present on 17 June. In all he had attended on 26 days of the session before the adjournment at the end of July 1661, nearly 41 per cent of the total.
Poulett was present when the session resumed on 20 Nov. 1661 but missed a call of the House on the 25th. He attended on 28 days of the session, a little over 22 per cent of the total, but his attendance was concentrated at its beginning and end. He did not attend after the Christmas recess until 5 May, having been granted leave of absence on 14 Jan. 1662.
Poulett was not listed as present on the opening day of the 1663 session on 18 Feb., although he was named to the committee for privileges. He was excused a call of the House on the 23rd owing to sickness and was first listed as present on 21 March. On 13 July Wharton classed him as doubtful in his forecast about the attempt of George Digby, 2nd earl of Bristol, to impeach Clarendon. He attended on 57 days of the session, two-thirds of the total and was named to a further nine committees.
Poulett was absent from the beginning of the 1664 session on 16 Mar. and was excused a call of the House on 4 April. He first attended on 26 Apr. and was present on 17 days of the session, 47 per cent of the total. He was absent from the 1664–5 session, being excused a call of the House on 7 Dec., it being recorded that he had registered a proxy, as indeed he had, on 24 Nov. with George Monck, duke of Albemarle.
Poulett’s absence from the House thereafter was almost certainly occasioned by failing health. In May 1665 Secretary Henry Bennet, Baron Arlington, was informed that he was too unwell to fulfil any of his county duties.
