Langston was a director of the Sun Fire Office from 1794 until his death.[1] He aimed to buy himself a place in Parliament, but never found a safe seat.[1] At the 1784 election he was returned after a contest as a Member of Parliament (MP) for Sudbury, an open borough with a reputation for venality where the government backed his candidacy.[3]
Having joined the opposition, Langston was no longer acceptable to Poulett,[4] so he turned instead to Minehead,[1] where opposition was mounting to the "overbearing conduct" of the borough's patron John Fownes Luttrell,[5] whose Dunster Castle-based family had dominated the borough for most of the period since its 16th-century enfranchisement.[6]
Langston bought some building land in Alcombe, within the borough, from a Quaker William Davis who had advertised for a wealthy challenger. There he rapidly built some houses to register voters, and nominated himself and his wife's brother-in-law Admiral Charles Morice Pole.[5]
At the election in 1796 John Fownes Lutrell held his own seat, but Langston defeated his brother Thomas Fownes Luttrell.[1]
Luttrell rallied his support by the next election in 1802, and defeated Langston, whose illegal treating of voters after the arrival of the writ, had not been enough to win. An election petition was prepared, but after a period of negotiations, Langston sold all his Minehead interests to Fownes Luttrell.[5]
At the general election in 1806, Langston returned to Bridgwater, where he won a contested election with Vere Poulett again returned as his running-mate. However, by 1807 the earl had disowned his brother's politics, and Langston withdrew.[4]
Langston never returned to Parliament, and died in 1812, aged about 54.
