Markham Spofforth was a British solicitor and political agent. He was Principal Agent of the Conservative Party from 1859 to 1870. A close adviser to Benjamin Disraeli, he rebuilt the Conservative Party's system of agents in the constituencies, which had been destroyed in the party split of 1846. He came to know Disraeli after being the assistant to Philip Rose, Disraeli's personal lawyer and the Conservative party's first agent. Spofforth took over the role as Principal Agent when Rose had to resign in 1859 following accusations of corruption.
