Brown, dubbed ‘Capey’ after his father at Eton, was a protégé of Lord Sandwich, to whom he wrote, ‘the best part of my life has been dedicated to your service, and my seats in Parliament, all taken at your request, have cost me much money’.
Sandwich provided Brown with an opening by dying in 1792 when his eldest surviving grandson was still a minor. Until 1794 he was a ‘sort of locum tenens’ for Viscount Hinchingbrooke. The arrangement was publicly ridiculed by ‘Verax’ (Lord Carysfort) who alleged that Brown ‘can never have any Capability to render even the slightest service being literally a mere mushroom sprung from a dung-hill in Stowe gardens’.
a very moderate request after Mr Brown held the seat in Parliament till my son came of age and then resigned it into his hands—besides having been a very useful magistrate and a friend to my family for these last twenty years in the county of Huntingdon.

In 1800, when Brown’s brother still had no living, Cornwallis claimed that Sandwich was afraid that if it were not procured, Brown would stir up an opposition to him in the county.
