New Romney was a parliamentary constituency in Kent, which elected two Members of Parliament (MPs) to the House of Commons from 1371 until 1832, when it was abolished by the Great Reform Act.
The Dering influence in New Romney seems mainly to have been achieved by letting out property to voters and their relatives at easy rents and without leases.
In 1761, for example, the despairing Whig MP, Rose Fuller, explained to Prime Minister Newcastle that he had no chance of re-election since Dering had turned against him, because "several of the governing men are graziers and the Deering and Furnese family have together a very great estate in the neighbouring marsh which is very profitable to and easy for tenants".

New Romney was abolished as a constituency by the Reform Act, the town being incorporated into the new Eastern Kent county division.
