Bouverie was first elected to parliament for Salisbury in 1761, a seat under the patronage of the Bouverie family, which he occupied until his nephew Viscount Folkestonecame of age and could take up the seat in 1771. In Parliament he followed an independent line. In 1763 he supported the radical MP John Wilkes when he was charged with seditious liable for an article attacking George III, but voted with Administration on the expulsion of Wilkes from parliament in 1769. At various times he was listed as a Whig supporter and at others as a Tory. Bouverie attempted to return to parliament in 1774 offering himself at Northampton hoping for the support of the Compton interest, but withdrew without making the canvass. Although he considered standing at a by-election in 1782 and the general election in 1784 he did not stand again until 1790 when he won one of the Northampton seats. Following his return to Parliament Bouverie became a staunch supporter of Charles James Fox and voted with him consistently. He was supported by his wife, a renowned London beauty and socialite who became a political hostess and close friend of other aristocratic supporters.
Personal life
As the second son, Bouverie had to some extent make his own way in the world which he did by his marriage to Harriet Falkner the daughter of Sir Everard Fawkener, ambassador to the Porte on 30 June 1764. Together, Edward and Harriet had three sons and five daughters, including:
Edward Bouverie, who inherited Delapré estate and married Catherine Castle, heiress and daughter of William Castle.
In 1811, a year after Bouverie died, his widow married Lord Robert Spencer, with whom Harriet had a long liaison. Their daughter Diana, who was considered to be Spencer's daughter, was left the bulk of Spencer's estate.
Delapré Abbey
On his marriage Bouverie bought Delapré Abbey for £22,000 from Sir Charles Hardy, Governor of New York, the husband of the Mary Tate, the last of the Tate family, who had owned the estate since their purchase of the former nunnery on its dissolution. At home Edward worked to develop the Delapré estate. In 1765/6 he enclosed the open fields at Hardingstone, making him one of the pioneers of the early inclosure movement in Northamptonshire. In the early 1770s Hunsbury Hill farm, which was part of the estate and an early model farm, was built. We may never know were Bouverie got the design for his new farm but it is clear that his architect provided quite an innovative and effective solution. Contributions were also made for re-roofing and rebuilding the chancel and the top of the tower local church of St Edmonds, Hardingstone.
