Deedes made his county cricket debut playing for Hampshire against Sussex and was dismissed by Jem Broadbridge in each innings.
Now 29 years of age, he was to play just two further first-class matches within the following calendar year, his final first-class appearance coming as a tailender in a combined Hampshire and Surrey team against Sussex in 1826.
Deedes' brother, John and son William also played first-class cricket.
Deedes was elected to House of Commons as a Member of Parliament (MP) for East Kent at an unopposed by-election March 1845.
However, Sir Edward Dering, a Liberal who won one of East Kent's two seats in 1852, resigned from the House of Commons on 1 December 1857, and Deedes was elected unopposed at the resulting by-election.
