Grant was born and spent his early childhood in Narberth, Pembrokeshire, moving to Yardley in 1812 following his mother’s marriage to the Rev. Henry Gwyther. Although not heir to the Philipps baronetcy, he was groomed to succeed its holder, his mother’s kinsman Lord Milford, a leader of the Blue or Whig party in Pembrokeshire (which he represented, 1786-1812) to the 20,000-acre Picton Castle estate, in preference to Rowland Philipps Laugharne of the Orlandon branch of the family. He was commissioned as a lieutenant in the Pembrokeshire yeomanry cavalry, 29 Dec. 1819, and shortly after he came of age in 1822 he was made a freeman and common councillor of Haverfordwest, where Milford retained a controlling interest.
Philipps voted against Catholic relief, 6 Mar., and the government’s corn bill, 2 Apr. 1827.
Ministers listed Philipps among the ‘good doubtfuls’, but later amended the entry to ‘enemy’. He was absent from the division on the civil list when they were brought down, 15 Nov., but presented petitions from Haverfordwest and north Pembrokeshire for the abolition of West Indian slavery, 21 Nov. 1830. He divided for the Grey ministry’s reform bill at its second reading, 22 Mar., and against Gascoyne’s wrecking amendment, 19 Apr., but failed to find an opportunity to present the Pembrokeshire reform petition entrusted to him (5 Apr.) before the dissolution, 23 Apr. 1831.
He voted for the reintroduced reform bill at its second reading, 6 July, and consistently for its details, including the enfranchisement of Merthyr as a contributory borough of Cardiff, which Welsh reformers criticized as inadequate, 10 Aug. 1831. He divided for the bill’s passage, 21 Sept., the second reading of the Scottish reform bill, 23 Sept., and Lord Ebrington’s confidence motion, 10 Oct. He adopted a lower profile during the second Pembrokeshire election when Owen again prevailed, but gave his interest and financial support to Greville as previously.
After a thorough canvass of the new Haverfordwest district constituency he was returned unopposed as a Liberal at the general election in December 1832.
