Charlton was Newcastle’s chief election agent in Nottinghamshire and his manager at Newark. For these services he received a place (not a sinecure) in the Ordnance at a salary of £400 p.a., which he exchanged in 1758 for a pension of £500 on Ireland; and in 1752 he was appointed chairman of committees with £500 p.a. out of secret service funds. In 1754 Newcastle procured a grant of £1,000 from secret service funds towards his election expenses, which appear to have amounted to about £1,700.
In March 1761 Charlton, who had now become unpopular at Newark, applied to Newcastle for leave to retire on grounds of ill health. Still, he wrote on 5 Mar.,
Charlton died February 1778.
